25 CVE

  1. CVE-2026-82343 6.1 Moyenne

    GNOME GIMP · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    A flaw was found in the file-psd plugin in GIMP. When processing a specially crafted PSD image file, the plugin does not properly validate the channel-count parameter. This incorrect validation leads to improper memory bounds checking, resulting in both a heap out-of-bounds read and a stack out-of-bounds access. This issue can result in an application crash, leading to a denial of service or a limited information disclosure of memory contents.

  2. CVE-2026-82330 6.1 Moyenne

    GNOME GIMP · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    A flaw was found in the file-pvr plugin in GIMP. When processing a specially crafted PVR image file, the VQ (compressed) decoder does not properly perform memory bounds checking. This missing validation results in a heap out-of-bounds read. This issue can result in an application crash, leading to a denial of service or a limited information disclosure of heap memory contents.

  3. CVE-2026-82328 6.1 Moyenne

    GNOME GIMP · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    A flaw was found in the file-ico plugin in GIMP. When processing a specially crafted ICO image file, the plugin does not properly validate the used_clrs (palette count) parameter. This incorrect validation leads to improper memory bounds checking, resulting in a heap out-of-bounds read. This issue can result in an application crash, leading to a denial of service or a limited information disclosure of heap memory contents.

  4. CVE-2026-82327 5.5 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9

    A flaw was found in libsolv, a dependency-resolution library used by RPM-based package managers such as dnf and zypper to work with .solv repository cache files. When libsolv rewrites a .solv cache file, it reads directory-id values from the file's compressed filelist data without validating that they fall within the expected range. A corrupted or specially crafted .solv cache file (for example, one left in a torn state after an unclean system shutdown) can cause an out-of-bounds memory write when a tool such as dnf, yum, or zypper next processes it. Successful exploitation is expected to result in a crash of the affected tool (denial of service); it is not expected to allow arbitrary code execution because the out-of-bounds write always stores a fixed, non-attacker-controlled value.

  5. CVE-2026-82324 6.1 Moyenne

    GNOME GIMP · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    A flaw was found in the file-iff (IFF/ILBM) plugin in GIMP. When processing a specially crafted IFF/ILBM image file, the plugin does not properly validate the HAM row size and improperly handles cases where the number of color planes (nPlanes) is zero. This causes a row size mismatch that bypasses memory bounds checking, resulting in heap out-of-bounds reads. This issue can result in an application crash, leading to a denial of service or a limited information disclosure of heap memory contents.

  6. CVE-2026-18393 5.4 Moyenne

    Red Hat Enterprise Linux AI (RHEL AI) 3 · Red Hat OpenShift AI (RHOAI)

    A flaw was found in FFmpeg. The tdsc_load_cursor() function writes beyond the bounds of a heap-allocated buffer when processing crafted TDSC cursor data. A remote attacker could exploit this by supplying a specially crafted video file, potentially leading to a denial of service or arbitrary code execution.

  7. CVE-2026-80179 5.9 Moyenne

    Red Hat Ansible Automation Platform 2 · Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 9 · Red Hat OpenShift AI (RHOAI)

    A flaw was found in jwcrypto. A remote attacker can send a specially crafted JSON Web Encryption (JWE) token containing numerous period delimiters. This malformed token can force the JWE.deserialize() function to allocate excessive memory, leading to a MemoryError. This issue results in a denial of service (DoS) for services that process untrusted JWE values.

  8. CVE-2026-81893 4.7 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    A flaw was found in gdk-pixbuf. When loading a specially crafted JPEG image containing chunked ICC profile markers, an error during ICC profile parsing can leave stale size metadata after the profile buffer is freed. A subsequent allocation in the same decode can cause an out-of-bounds write, potentially crashing the application. To exploit this flaw, an application using gdk-pixbuf must process the malicious JPEG image. Affected version >= 2.26.4

  9. CVE-2026-78002 7.5 Élevée

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 10.0 Extended Update Support · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 8.8 Telecommunications Update Service

    A flaw was found in rsyslog. An unauthenticated remote attacker can trigger a heap buffer overflow in the RainerScript `replace()` function by sending specially crafted syslog messages. This vulnerability arises from an incorrect buffer size calculation during string replacement, causing memory corruption. Successful exploitation can lead to a denial of service (DoS) for the affected system.

  10. CVE-2026-5680 7.5 Élevée

    Red Hat JBoss Enterprise Application Platform 8.1.8.GA · Red Hat JBoss Enterprise Application Platform 8.1 for RHEL 10 · Red Hat JBoss Enterprise Application Platform 8.1 for RHEL 8 · Red Hat JBoss Enterprise Application Platform 8.1 for RHEL 9

    A flaw was found in Undertow. A remote attacker could exploit this vulnerability by sending specially crafted WebSocket messages with permessage-deflate negotiated. This could lead to excessive memory consumption due to the PerMessageDeflateFunction.largerBuffer() method using exponential doubling, resulting in a Denial of Service (DoS) for the affected application.

  11. CVE-2026-79902 5.5 Moyenne

    GNOME GIMP · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    A flaw was found in the Seattle FilmWorks plugin in GIMP. When processing a specially crafted SFW image file, the plugin allocates a Variable-Length Array (VLA) on the stack without integer overflow checks, causing an unbounded stack allocation. This issue leads to an application crash, resulting in a denial of service.

  12. CVE-2026-80186 7.6 Élevée

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    A stack-based buffer overflow vulnerability exists in BlueZ, the Linux Bluetooth protocol stack. A remote user within Bluetooth radio range can send a specially crafted Extended Inquiry Response (EIR) packet that causes a buffer overflow when the target device performs Bluetooth discovery. This vulnerability can lead to a Denial of Service (DoS) by crashing the bluetoothd service and may allow for arbitrary code execution.

  13. CVE-2026-80185 5.7 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    BlueZ sdp-xml.c type confusion via RegisterProfile(ServiceRecord) can crash bluetoothd (local DoS): a crafted nested ServiceRecord can corrupt the SDP XML parser stack so scalar union data is treated as a sequence pointer, allowing a local caller to crash bluetoothd.

  14. CVE-2026-80101 4.4 Moyenne

    GNOME GIMP · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    A flaw was found in the file-xwd plugin in GIMP. When processing a specially crafted XWD image file, the plugin validates the image width and bytes-per-line parameters independently rather than ensuring their combined values are consistent with the allocated buffer size. This incorrect validation leads to improper bounds checking, causing a heap out-of-bounds read. This issue can result in an application crash, leading to a denial of service or a limited information disclosure of heap memory contents into the produced image.

  15. CVE-2026-77680 5.3 Moyenne

    Red Hat Enterprise Linux 10

    An algorithmic complexity flaw exists in libsoup's HTTP Range header processing that persists after the CVE-2025-32907 fix. CVE-2025-32907 addressed memory amplification when a client repeated the same range many times in a single Range header. Commit 9bb92f7a corrected merge correctness in soup_message_headers_get_ranges_internal() in libsoup/soup-message-headers.c, but the coalescing loop still removes merged ranges using g_array_remove_index() for each coalesced element. Because GArray is contiguous, each mid-array removal performs an O(N) memmove. When many identical satisfiable ranges are supplied (for example bytes=0-0 repeated thousands of times), the loop performs O(N²) work coalescing them into a single range. The vulnerable path is reachable server-side from handle_partial_get() in libsoup/server/http1/soup-server-message-io-http1.c when a SoupServer handler returns HTTP 200 with a non-empty body. No authentication is required. The number of ranges is bounded only by the maximum request header size (~100 KiB), allowing roughly 25,000 ranges per request. Reporter measurements on libsoup HEAD containing the CVE-2025-32907 fix show ~90 ms single-core CPU per such request at the wire maximum, blocking the server's event loop for that duration. This is a CPU exhaustion / availability issue only. No memory corruption or information disclosure occurs. Affected: libsoup versions containing the CVE-2025-32907 fix but not merge request !550. Fixed upstream: MR !550 merged 2026-08-20, replacing per-element removal with O(N) in-place compaction and rejecting Range headers requesting more than 200 ranges.

  16. CVE-2026-79992 7.8 Élevée

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9 · Red Hat Enterprise Linux 6

    A flaw was found in Emacs TRAMP. A local attacker could exploit this vulnerability by processing maliciously crafted filenames. This occurs because TRAMP concatenates login arguments without proper sanitization, which are then passed to a local shell. Successful exploitation could lead to arbitrary code execution.

  17. CVE-2026-79655 7.8 Élevée

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    A flaw was found in sos clean, a utility within the sos package. This vulnerability allows a local attacker to perform arbitrary file creation or overwrite. By crafting a malicious tar archive, an attacker can exploit a path traversal issue during tar extraction, where symlink and hardlink targets are not properly validated. This enables the attacker to write files to arbitrary locations on the system with the privileges of the sos clean process, which often runs as root.

  18. CVE-2026-78701 6.5 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 9 · Red Hat Directory Server 13.2 · Red Hat Directory Server 11

    A flaw was found in 389-ds-base. A remote, authenticated attacker could exploit a vulnerability in the Simple Authentication and Security Layer (SASL) UNBIND process. By sending a specially crafted request, the attacker can cause a connection to stall, leading to resource exhaustion and a Denial of Service (DoS) for the server.

  19. CVE-2026-78322 6.5 Moyenne

    Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    A flaw was found in file-roller. When opening or extracting a malicious 7z or RAR archive containing a file entry with an excessively long path, file-roller's progress-line parsing copies the path into a fixed-size stack buffer using an unbounded string copy. This can trigger a stack buffer overflow and cause file-roller to terminate, resulting in a denial of service. To exploit this flaw, a victim must open or extract the crafted archive using file-roller.

  20. CVE-2026-78475 6.1 Moyenne

    GNOME GIMP · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    A flaw was found in the file-pix (ESM) plugin in GIMP. When processing a specially crafted PIX image file, the plugin allocates a Variable-Length Array (VLA) on the stack without proper bounds checking, causing an unbounded stack allocation followed by a 21-byte stack over-read. This can result in a denial of service due to stack exhaustion and a limited information disclosure of stack memory contents into an intermediate file.

  21. CVE-2026-78465 7.0 Élevée

    GNOME GIMP · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    A flaw was found in the file-pcx plugin in GIMP, affecting 32-bit builds only. When processing a PCX image file, the plugin calculates memory allocation sizes based on the image dimensions and the number of color planes. If a crafted file sets the number of planes to 4 alongside sufficiently large dimensions, the calculation exceeds the 32-bit integer limit and overflows, resulting in an undersized heap-based buffer allocation. This integer overflow issue results in a heap-based buffer overflow when the plugin subsequently writes image data into the undersized buffer, causing memory corruption, potentially leading to arbitrary code execution or a denial of service.

  22. CVE-2026-19685 7.1 Élevée

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    NetworkManager did not apply the private_user restriction to the 802-1x.ca-path and phase2-ca-path directory-valued connection properties. This incomplete fix for CVE-2025-9615 allows an unprivileged local user to point a private WPA-Enterprise (802.1X) connection profile's CA path at an attacker-controlled directory, bypassing server certificate validation and enabling credential theft via a rogue access point.

  23. CVE-2026-78376 8.8 Élevée

    WebKit · WebKitGTK · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9

    A flaw was found in WebKitGTK. Processing malicious web content can cause a use-after-free issue due to improper memory handling and result in memory corruption.

  24. CVE-2026-78367 7.0 Élevée

    Red Hat Hardened Images · Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7

    A vulnerability was found in RPM's rpmbuild tarball processing. When processing a crafted source archive, the getTarSpec() function in tools/rpmbuild.cc passes an attacker-controlled tar archive member name to rpmExpand() as part of a %{basename:...} macro expression. A specially crafted .spec member name can therefore inject RPM macros, including Lua expressions, resulting in arbitrary code execution with the privileges of the user running rpmbuild. This can be exploited when a victim or automated build system processes an attacker-controlled source tarball using rpmbuild tarball mode (such as -ts, -ta, or -tb).

  25. CVE-2026-78323 6.5 Moyenne

    Red Hat Certificate System 10 · Red Hat Certificate System 11 · Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 6

    A flaw was found in JSS (Java Security Services). The JSSTrustManager class does not verify NSS trust flags when validating CA certificates, allowing certificates present in the NSS database without TRUSTED_CA flags to be accepted as trust anchors for TLS connections. In non-default configurations where certificate revocation checking is disabled, this could allow a man-in-the-middle attacker to forge certificates accepted by PKI client connections.
