Echo: libde265: security update to 1.0.15-1+e6

high Tenable Self-Hosted Container Security Plugin ID 459143

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 1.0.20, a crafted
 H.265 bitstream can cause an out-of-bounds array write in
 `decoder_context::process_reference_picture_set()` (`libde265/decctx.cc:1376`). The root cause is a
 missing aggregate bound check on predicted short-term reference picture set entries. Individual list sizes
 are validated, but the combined count after predicted RPS construction can exceed the 16-entry `PocStFoll`
 array, writing at index 16. Version 1.0.20 patches the issue. (CVE-2026-49295)

Solution

Update the libde265 library and its related packages to version 1.0.15-1+e6 or later.
