Echo: libheif: security update to 1.19.8-1

medium Tenable Self-Hosted Container Security Plugin ID 461876

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. Prior to version 1.22.0,
 `Track::init_sample_timing_table()` in `libheif/sequences/track.cc` stores an out-of-bounds chunk index
 (`m_chunks.size()`) into `m_presentation_timeline` when the number of chunks defined in the `stco` box is
 less than the number of samples in `stsz`. A subsequent call to
 `heif_track_get_next_raw_sequence_sample()` reads `m_chunks[chunk_idx]` with that OOB index, causing a
 heap-buffer-overflow. Version 1.22.0 fixes the issue. (CVE-2026-47254)

Solution

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