Echo: libheif: security update to 1.19.8-1+e3

high Tenable Self-Hosted Container Security Plugin ID 464294

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. Versions 1.21.2 and prior contain a heap-
buffer-overflow (write) vulnerability in the grid tile compositing, allowing an attacker to write 64 bytes
of fully attacker-controlled data past the end of a chroma plane heap allocation by crafting a HEIF/AVIF
file with a 1×4 grid of odd-height tiles. The overflow is triggered during normal image decoding with
default build configuration. The written bytes are chroma (Cb/Cr) pixel values from the attacking tile,
giving the attacker full control over the overflow content. This issue has been fixed in version 1.22.0.
(CVE-2026-32740)

Solution

Update the libheif library and its related packages to version 1.19.8-1+e3 or later.
