Echo: libde265: security update to 1.0.15-1+e13

high Tenable Cloud Security Plugin ID 473632

Description

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

 - libde265 commit 4d45a6b contains a NULL pointer dereference vulnerability in the NAL parsing path. When
 de265_push_NAL() is called with a zero-length NAL unit, the resulting NAL_unit may retain a NULL backing
 buffer, which is subsequently passed as the destination argument to memcpy() in NAL_unit::set_data().
 Although the copy length is zero, this violates the nonnull requirement of memcpy() and results in
 undefined behavior, causing process termination in UBSan-instrumented builds and denial of service.
 (CVE-2026-88373)

Solution

Update the libde265 library and its related packages to version 1.0.15-1+e13 or later.
