Echo: libheif: security update to 1.19.8-1

medium Tenable Self-Hosted Container Security Plugin ID 462897

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 below, a crafted
 800-byte HEIF sequence file causes an infinite loop in Box_stts::get_sample_duration(), consuming 100% CPU
 indefinitely with zero progress, leading to DoS. The loop has no iteration limit or timeout and is
 triggered during file open (parsing) - before any user interaction or image decoding. The process stays
 alive (no crash, no error logged), making it invisible to crash-based monitoring. This issue has been
 fixed in version 1.22.0. (CVE-2026-32739)

Solution

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