Echo: libde265: security update to 1.0.15-1+e5

high Tenable Self-Hosted Container Security Plugin ID 457198

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 1.1.0, a crafted
H.265 bitstream with large SPS dimensions and 16-bit bit depth causes a signed integer overflow in
`de265_image_get_buffer()` (`libde265/image.cc:128`). The overflow wraps the plane allocation size to a
small value (~1 KB), but the subsequent `fill_image()` call computes the real size using `size_t`, writing
~4 GB into the undersized heap buffer. Version 1.1.0 patches the issue. (CVE-2026-49346)

Solution

Update the libde265 library and its related packages to version 1.0.15-1+e5 or later.
