Palo Alto Networks GlobalProtect App

A local privilege escalation vulnerability in the Palo Alto Networks GlobalProtect™ app enables a local user to escalate their privileges to root on macOS. This enables a non-administrative user to execute arbitrary commands with administrative privileges. The GlobalProtect app on Linux, Windows, iOS, Android and Chrome OS is not affected by this vulnerability.

A type confusion vulnerability in Palo Alto Networks GlobalProtect™ app on Windows enables a local user with low privileges to cause a denial of service (DoS) condition. The GlobalProtect™ app on Linux, macOS, iOS, Android, and Chrome OS is not affected by this vulnerability.

WeGIA is a web manager for charitable institutions. Prior to 3.8.6, the pre-installation web/instalador/instalador.php endpoint is reachable before config.php exists and processes unauthenticated installation POST data. In the Linux reinstall flow, a crafted usuario value reaches a command executed by shell_exec(). The installer also writes attacker-controlled values into executable config.php and concatenates the database name nomebd into a CREATE DATABASE statement. Successful exploitation can execute commands as the web-server user, persist attacker-controlled PHP configuration, and alter or disrupt the application and its data. This issue is fixed in version 3.8.6.

A flaw was found in the DPDK nfp vDPA driver. Stack and heap buffers sized for a single queue pair can be overflowed when more virtqueues are configured, leading to a host crash or memory corruption.

A flaw was found in DPDK lib/vhost vhost-crypto. Integer overflow in chain length checks, and missing length checks on the RSA path, can overflow a host buffer in the vhost-crypto backend.

A flaw was found in DPDK lib/vhost vhost-crypto. Write-back chain cleanup can follow an uninitialized next pointer when mapping a guest descriptor fails, causing the host vhost-crypto process to hang or crash.

A flaw was found in DPDK lib/vhost vhost-crypto. A guest can supply an avail-ring descriptor index that is used without bounds checking, causing an out-of-bounds write in the host vhost-crypto backend.

A flaw was found in DPDK lib/vhost vhost-crypto. Session cleanup can leave a stale cached session pointer, and the data path does not check the session type before attaching it, leading to use-after-free or type confusion in the host vhost-crypto backend.

A flaw was found in DPDK lib/vhost. A guest with runt RX descriptors can underflow the copy length in vhost enqueue, causing a denial of service in a shared vhost backend such as OVS-DPDK.

A flaw was found in evolution-data-server. Calendar events containing a file:// URI in their ATTACH property automatically read the targeted local file, base64-encode its contents and upload it back to the server when the event is saved. There are no file path restrictions or checks to verify whether the attachment originally came from the server or was added locally. This allows an attacker with access to a shared CalDAV calendar to exfiltrate arbitrary files the user has access to when interacting with malicious calendar events.

A flaw was found in the DPDK vhost library. When handling a virtio indirect descriptor table, the host reads the table length more than once from guest memory and can allocate a host copy before validating that length. A guest that changes the length between those reads, or that supplies an out-of-range next index on a small host copy in the vDPA relay path, can cause the host vhost process to walk past the validated mapping or heap copy. That can crash or disrupt the vhost process. Out-of-bounds bytes are consumed as descriptor fields for GPA translation and are not returned to the guest as payload. This is a residual issue in the non-contiguous indirect descriptor copy path introduced as part of the CVE-2018-1059 fix.

A flaw was found in DPDK lib/vhost. Memory size is not adequately validated before mmap during vhost memory-region setup, which can lead to a host crash or memory corruption.

A flaw was found in the clevis PKCS#11 pin. The clevis-pkcs11-afunix-socket-unlock daemon logs LUKS disk encryption passphrases in plaintext to a log file. The log file is created without restrictive permissions, making it world-readable under the default process umask. A local attacker can read the log file to obtain the LUKS passphrase.

A flaw was found in GStreamer's H.266 codec parser library (libgstcodecparsers). An out-of-bounds write vulnerability exists in the DCI parsing function, where a reserved field value is incorrectly accepted, causing the parser to write beyond the bounds of an internal structure. An attacker could exploit this by providing a specially crafted H.266 bitstream to a third-party application that uses this library API, potentially causing a crash or memory corruption. No standard GStreamer pipeline element currently invokes the affected code path.

A flaw was found in the clevis PKCS#11 pin. The clevis-decrypt-pkcs11 script passes the PKCS#11 token PIN as a command-line argument to pkcs11-tool, making it visible to any local user through process listing or the /proc filesystem.

A flaw was found in the clevis PKCS#11 pin. The clevis-luks-pkcs11-askpin script writes the PKCS#11 token PIN in plaintext to a file without setting restrictive permissions. Under the default process umask, the file is world-readable. Additionally, the PIN file is not reliably cleaned up if the decryption script exits early, leaving the PIN accessible indefinitely.

A flaw was found in the clevis PKCS#11 pin. The clevis-pkcs11-afunix-socket-unlock daemon creates AF_UNIX sockets without explicit permission restrictions or peer credential verification. Under a permissive process umask, any local user can connect to the control socket and inject arbitrary device/key pairs, or connect to the data socket to receive LUKS passphrases.

A flaw was found in the GStreamer multimedia framework's ASF muxer plugin (asfmux). When writing string metadata tags containing Unicode characters outside the Basic Multilingual Plane (such as emoji) to an ASF container, the plugin incorrectly calculates the buffer size needed for the UTF-16LE representation. The size calculation assumes each Unicode code point requires 2 bytes, but non-BMP characters require 4 bytes (surrogate pairs). This leads to a heap out-of-bounds write when the actual UTF-16LE conversion is written into the undersized buffer. An attacker could exploit this by providing media with crafted metadata tags to an application that transcodes or remuxes to ASF format while preserving metadata, potentially causing a denial of service or limited memory corruption.
