Echo: libheif: security update to 1.19.8-1

high Tenable Self-Hosted Container Security Plugin ID 460897

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 1.23.0, a crafted HEIF
sequence accepted by heif_context_read_from_memory() with the msf1 sequence brand can cause unbounded heap
allocation. In libheif/sequences/seq_boxes.cc, Box_stsz::parse() applies max_sequence_frames only to
variable-size samples, so fixed-size mode accepts an attacker-controlled sample_count without a bound. In
libheif/sequences/track.cc, Track::load() also adds current_sample_idx and samples_per_chunk in 32-bit
arithmetic, allowing the consistency check to be bypassed by wraparound. The resulting values reach the
Chunk::Chunk() allocation path, which can consume gigabytes of memory and crash or stall the process
through memory exhaustion. This issue is fixed in version 1.23.0. (CVE-2026-50142)

Solution

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