Echo: libheif: security update to 1.23.2-1

high Tenable Cloud Security Plugin ID 472794

Description

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

 - libheif is a HEIF and AVIF file format decoder and encoder. From 1.19.0 until 1.23.2, crafted HEIF or AVIF
 mime metadata and unci image data can cause decompress_brotli() and do_inflate() to grow accumulated
 output without an effective size limit or MemoryHandle accounting. The brotli path has no output bound,
 while the zlib path checks only a small temporary buffer in a branch that valid streams do not reach, and
 overlapping icef units can decompress the same payload repeatedly.
 HeifContext::interpret_heif_file_images() processes multiple compressed metadata items during file
 opening, allowing a small file to consume unbounded memory and terminate the process. This issue is fixed
 in version 1.23.2. (CVE-2026-84384)

Solution

Update the libheif library and its related packages to version 1.23.2-1 or later.
