Echo: libde265: security update to 1.0.15-1+e8

medium Tenable Cloud Security Plugin ID 455452

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. Versions prior to 1.0.19 have a heap
 buffer overflow (out-of-bounds READ) exists in `decoder_context::decode_slice_unit_WPP()` in
 `libde265/decctx.cc`. When decoding a WPP (Wavefront Parallel Processing) HEVC slice, `ctbAddrRS` is
 computed as `ctbRow * ctbsWidth` inside the entry-point loop. If the PPS/SPS headers are crafted so that
 this value exceeds `pps.CtbAddrRStoTS.size()`, the subsequent array access `pps.CtbAddrRStoTS[ctbAddrRS]`
 reads past the end of the allocated vector, triggering a heap-buffer-overflow confirmed by
 AddressSanitizer. Version 1.0.19 patches the issue. (CVE-2026-45383)

Solution

Update the libde265 library and its related packages to version 1.0.15-1+e8 or later.
