There are 5 open security issues in bookworm.
2 important issues:
- CVE-2026-33164:
libde265 is an open source implementation of the h.265 video codec. Prior to version 1.0.17, a malformed H.265 PPS NAL unit causes a segmentation fault in pic_parameter_set::set_derived_values(). This issue has been patched in version 1.0.17.
- CVE-2026-33165:
libde265 is an open source implementation of the h.265 video codec. Prior to version 1.0.17, a crafted HEVC bitstream causes an out-of-bounds heap write confirmed by AddressSanitizer. The trigger is a stale ctb_info.log2unitSize after an SPS change where PicWidthInCtbsY and PicHeightInCtbsY stay constant but Log2CtbSizeY changes, causing set_SliceHeaderIndex to index past the allocated image metadata array and write 2 bytes past the end of a heap allocation. This issue has been patched in version 1.0.17.
3 issues left for the package maintainer to handle:
- CVE-2023-51792:
(needs triaging)
Buffer Overflow vulnerability in libde265 v1.0.12 allows a local attacker to cause a denial of service via the allocation size exceeding the maximum supported size of 0x10000000000.
- CVE-2024-38949:
(postponed; to be fixed through a stable update)
Heap Buffer Overflow vulnerability in Libde265 v1.0.15 allows attackers to crash the application via crafted payload to display444as420 function at sdl.cc
- CVE-2024-38950:
(postponed; to be fixed through a stable update)
