Echo: libheif: security update to 1.19.8-1

medium Tenable Self-Hosted Container Security Plugin ID 457645

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. In versions 1.21.2 and prior, a crafted HEIF
 sequence file where the saiz box declares more samples than actually exist in the track's chunk table
 causes a heap-buffer-overflow (out-of-bounds read) in the SampleAuxInfoReader constructor. The
 SampleAuxInfoReader constructor iterates over saiz->get_num_samples() samples but doesn't validate that
 this count is consistent with the number of chunks in the chunks vector. When saiz declares more samples
 than the chunks cover, the loop increments current_chunk past chunks.size(), causing an out-of-bounds read
 on the chunks vector. The vulnerability is triggered during file parsing (heif_context_read_from_file)
 without any additional user interaction. Any application using libheif to open untrusted HEIF files is
 affected. This issue has been fixed in version 1.22.0. (CVE-2026-41071)

Solution

Update the libheif library and its related packages to version 1.19.8-1 or later.
