getkin kin-openapi

kin-openapi is a Go project for handling OpenAPI files. From 0.124.0 until 0.142.0, openapi3filter.sliceMapToSlice in openapi3filter/req_resp_decoder.go converts attacker-controlled sparse indexes from a deepObject query parameter into a dense slice by allocating entries from zero through the largest supplied index, after which buildResObj creates another slice of the same length. This allocation occurs before schema validation, so maxItems does not prevent it. An unauthenticated client can send a small query such as param[items][50000000]=x to an endpoint whose deepObject schema contains an array, forcing multi-gigabyte heap allocation and causing an OOM kill or restart loop. Other request-body encodings and styled parameters that do not produce bracketed integer indexes are not affected. This issue is fixed in version 0.142.0.

getkin kin-openapi

kin-openapi is a Go project for handling OpenAPI files. From 0.10.0 until 0.141.0, openapi3filter.convertParseError in openapi3filter/validation_error_encoder.go dereferences e.Parameter.In without checking whether e.Parameter is nil. A malformed non-string scalar field in a multipart/form-data request body produces a nested ParseError with a nil RequestError.Parameter, and applications that render the validation error through openapi3filter.ConvertErrors or ValidationErrorEncoder panic. An unauthenticated client can repeatedly send such requests to deny service when the application lacks a recovery boundary. JSON request bodies and applications that do not use these error-rendering helpers are not affected. This issue is fixed in version 0.141.0.

Remote Utilities Pte. Ltd. Remote Utilities Host

Remote Utilities Host <=7.7.3.0 sets insecure ACLs on all DLL files in the installation directory (C:\Program Files (x86)\Remote Utilities - Host\), granting FULL CONTROL (F) to the built-in Everyone group (BUILTIN\Everyone, S-1-1-0). A Windows service running as NT AUTHORITY\SYSTEM loads DLLs from this directory. The DLLs are file-locked at runtime, but a race window exists when the service is stopped (e.g. during a software update or following a crash), during which a local unprivileged attacker can replace a DLL with a malicious payload. Upon service restart, the payload executes as NT AUTHORITY\SYSTEM. The DLL confirmed as actively loaded during testing is libasset32.dll. Additional DLLs in the same directory (eventmsg.dll, libcodec32.dll, vp8encoder.dll, vp8decoder.dll, webmvorbisdecoder.dll, webmvorbisencoder.dll, webmmux.dll) share identical insecure permissions.

capstone-engine capstone

Capstone is a disassembly framework. In 6.0.0-Alpha9 and earlier, Capstone's arch/SH/SHDisassembler.c SH floating-point decoders such as opFADD, opFMUL, and opFSUB call set_reg() and set_reg_n() using sh_info.op.op_count without checking the fixed-size operands[] array. Repeated crafted instructions processed through cs_disasm_iter() or cs_disasm() with CS_ARCH_SH, CS_MODE_SH2A or CS_MODE_SH4A, CS_MODE_SHFPU, and CS_OPT_DETAIL can increment the operand count beyond the 176-byte sh_info allocation and perform a four-byte heap buffer overflow write. The corruption can crash the process and may enable code execution depending on heap layout. This issue is fixed in version 6.0.0-Alpha10.
