Echo: libheif: security update to 1.19.8-1

medium Tenable Cloud Security Plugin ID 459606

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 1.23.0 and earlier, a crafted HEIF sequence
accepted by heif_context_read_from_memory() can leave the context with no registered sequence tracks and
crash when heif_context_get_track(ctx, 0) is called. HeifContext::get_track() in libheif/context.cc
executes assert(has_sequence()) before its normal error handling, so assert-enabled builds abort instead
of allowing the public wrapper in libheif/api/libheif/heif_sequences.cc to return null. In release builds,
removing the assertion lets the track_id zero path dereference m_tracks.begin()->second on an empty map,
which is undefined behavior and typically crashes. The issue is reachable through documented public APIs
after parsing attacker-controlled bytes. This issue is fixed in version 1.23.1. (CVE-2026-62377)

Solution

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