medium Tenable Cloud Security Plugin ID 465093

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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.
 (CVE-2026-33165)

Solution

Update the libde265 library and its related packages to version 1.0.15-1+e2 or later.
