This package contains plug-ins that are not tested well enough yet, or the code is not of good...

CVE-2026-12891

A flaw was found in the GStreamer gst-plugins-bad package. When processing a malformed H.266/VVC video stream with a crafted aspect ratio indicator value, the H.266 parser performs an out-of-bounds read of up to 8 bytes from adjacent memory. This flaw allows an attacker to craft a malicious H.266...

CVE-2026-12891: Out-of-bounds Read

A flaw was found in the GStreamer gst-plugins-bad package. When processing a malformed H.266/VVC video stream with a crafted aspect ratio indicator value, the H.266 parser performs an out-of-bounds read of up to 8 bytes from adjacent memory. This flaw allows an attacker to craft a malicious H.266...

CVE-2026-12892: Out-of-bounds Read

A flaw was found in GStreamer's gst-plugins-bad package. When processing a specially crafted H.264 video file containing malformed MVC or SVC extension slice NAL units, a 1-byte heap out-of-bounds read can occur during parsing. This happens when the parser attempts to check slice boundary...

ROS-20260622-73-0040

The vulnerability of the h.265 Libde265 implementation lies in the copying of buffers without checking the input data. Exploiting this vulnerability can allow an attacker to cause a service failure...

Ubuntu 26.04 LTS : GStreamer Bad Plugins vulnerabilities (USN-8446-1)

The remote Ubuntu 26.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8446-1 advisory. It was discovered that GStreamer Bad Plugins incorrectly handled parsing H.266/VVC picture partition data. An attacker could use this issue to cause...

CVE-2026-49337

libde265 is an open source implementation of the h.265 video codec. Prior to version 1.0.20, a crafted sequence of H.265 NAL units causes decodercontext::readsliceNAL libde265/decctx.cc:481 to attach slice headers to a finished picture object that has no active image unit, resulting in...

UBUNTU-CVE-2026-49337

libde265 is an open source implementation of the h.265 video codec. Prior to version 1.0.20, a crafted sequence of H.265 NAL units causes decodercontext::readsliceNAL libde265/decctx.cc:481 to attach slice headers to a finished picture object that has no active image unit, resulting in...

Integer Overflow or Wraparound

Overview Affected versions of this package are vulnerable to Integer Overflow or Wraparound via the de265imagegetbuffer function when processing a crafted H.265 bitstream containing large SPS dimensions and 16-bit bit depth. An attacker can cause a heap buffer overflow by supplying a specially...

CVE-2026-49295 libde265 has an out-of-bounds write in process_reference_picture_set via predicted short-term RPS

libde265 is an open source implementation of the h.265 video codec. Prior to version 1.0.20, a crafted H.265 bitstream can cause an out-of-bounds array write in decodercontext::processreferencepictureset libde265/decctx.cc:1376. The root cause is a missing aggregate bound check on predicted...

CVE-2026-49346: Integer Overflow or Wraparound

libde265 is an open source implementation of the h.265 video codec. Prior to version 1.1.0, a crafted H.265 bitstream with large SPS dimensions and 16-bit bit depth causes a signed integer overflow in de265imagegetbuffer libde265/image.cc:128. The overflow wraps the plane allocation size to a sma...

CVE-2026-49295: Out-of-bounds Write

libde265 is an open source implementation of the h.265 video codec. Prior to version 1.0.20, a crafted H.265 bitstream can cause an out-of-bounds array write in decodercontext::processreferencepictureset libde265/decctx.cc:1376. The root cause is a missing aggregate bound check on predicted...

CVE-2026-49337: Allocation of Resources Without Limits or Throttling

libde265 is an open source implementation of the h.265 video codec. Prior to version 1.0.20, a crafted sequence of H.265 NAL units causes decodercontext::readsliceNAL libde265/decctx.cc:481 to attach slice headers to a finished picture object that has no active image unit, resulting in...

SUSE CVE-2026-53701

An out-of-bounds write vulnerability was found in GStreamer's H.266/VVC PPS picture partition parser in gst-plugins-bad. In the multi-slice-in-tile processing of gsth266parserparsepicturepartition gsth266parser.c, the loop iterates without checking that the slice index stays within bounds, writin...

CVE-2026-53702

A stack buffer overflow flaw was found in the GStreamer H.265 codec parser library gst-plugins-bad. When parsing a buffering period SEI message, the parser uses an incorrect loop bound derived from cpbcntminus1i the loop index instead of the sub-layer 0 CPB count cpbcntminus10 from the referenced...
