Echo: libheif: security update to 1.23.2-1

high Tenable Self-Hosted Container Security Plugin ID 472743

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 1.23.2, when WITH_UNCOMPRESSED_CODEC
 is enabled, heif_context_add_image_tile() accepts an independently constructed tile whose component-plane
 dimensions do not match the tile geometry established by the prototype image.
 ImageItem_uncompressed::add_image_tile() passes that tile directly to unc_encoder::encode_tile(), which
 lacked the check_component_sizes() gate and sizes its output from the configured tile geometry while
 copying the tile's actual component-plane dimensions. An oversized component plane can therefore make
 unc_encoder_component_interleave::encode_tile() copy attacker-controlled data beyond the heap output
 buffer. This issue is fixed in version 1.23.2. (CVE-2026-84444)

Solution

Update the libheif library and its related packages to version 1.23.2-1 or later.
