Use of Uninitialized Resource

Overview Affected versions of this package are vulnerable to Use of Uninitialized Resource in the avdynamichdrplustot35 function when processing HDR10+ metadata. An attacker can access sensitive process memory by supplying crafted Matroska T.35 BlockAdditional or HEVC/AV1 SEI metadata, causing...

DEBIAN-CVE-2026-107676

FFmpeg through 9.0.2 contains an uninitialized memory disclosure vulnerability in avdynamichdrplustot35 that leaves up to three payload bytes uninitialized when tonemappingflag is 0. Attackers can supply crafted Matroska T.35 BlockAdditional or HEVC/AV1 SEI metadata so that remuxing or transcodin...

CVE-2026-87875

The cupsUTF32ToUTF8 function in CUPS's cups/transcode.c lacks a source-length bound and can read past the end of the source buffer, resulting in a heap out-of-bounds read. This is reachable via SNMP supply-description parsing in backend/snmp-supplies.c with attacker-controlled content...

gRPC Erlang package's path bindings are overridable by query string and request body

Summary In the HTTP-to-gRPC transcoding layer of the grpc Hex package, query-string and request-body parameters can silently overwrite path-bound fields when building the decoded protobuf request struct. An authenticated attacker who can reach a transcoded endpoint can substitute any path-bound...

JLSEC-2026-1364 Wasmtime has out-of-bounds write or crash when transcoding component model strings

Impact Wasmtime's implementation of transcoding strings between components contains a bug where the return value of a guest component's realloc is not validated before the host attempts to write through the pointer. This enables a guest to cause the host to write arbitrary transcoded string bytes...

JLSEC-2026-1354 Wasmtime: Heap OOB read in component model UTF-16 to latin1+utf16 string transcoding

Summary Wasmtime contains a vulnerability where when transcoding a UTF-16 string to the latin1+utf16 component-model encoding it would incorrectly validate the byte length of the input string when performing a bounds check. Specifically the number of code units were checked instead of the byte...

JLSEC-2026-1355 Wasmtime: Panic when transcoding misaligned utf-16 strings

Impact Wasmtime's implementation of transcoding strings into the Component Model's utf16 or latin1+utf16 encodings improperly verified the alignment of reallocated strings. This meant that unaligned pointers could be passed to the host for transcoding which would trigger a host panic. This panic ...

libaom: libaom: heap buffer overflow in AV1 encoder first-pass stats buffer via LAP mode

A heap buffer overflow vulnerability was found in libaom, the reference AV1 codec implementation. A flaw in the AV1 encoder's Look-Ahead Processing LAP mode causes the first-pass stats ring buffer wrap-around guard to be bypassed when glaginframes is set to 1 or higher. This results in a 232-byte...
