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-2026-49346 libde265 has a heap buffer overflow in de265_image_get_buffer via SPS dimension integer overflow

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-2026-49346

CVE-2026-49346 affects libde265 up to version 1.0.x; a crafted H.265 bitstream with large SPS dimensions and 16-bit depth triggers a signed integer overflow in de265_image_get_buffer(), causing an undersized allocation (~1 KB) but later writing ~4 GB due to size_t math in fill_image. This is fixe...

CVE-2026-49337

CVE-2026-49337 affects libde265 prior to 1.0.20. A crafted sequence of H.265 NAL units lets decoder_context::read_slice_NAL() attach slice headers to a finished picture object with no active image unit, causing attacker-controlled unbounded heap growth. The headers are retained until the picture ...
