Echo: libheif: security update to 1.19.8-1+e6

medium Tenable Self-Hosted Container Security Plugin ID 459445

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 prior, the inline mask
 parsing code in `libheif/region.cc` contains an integer overflow. Both `width` and `height` are `unsigned
 int` (32-bit) values parsed from the HEIF file. Their product can exceed `UINT32_MAX`, wrapping to a small
 value before the division by 8. This causes an undersized buffer allocation, leading to out-of-bounds
 memory access when the mask data is later interpreted as a `width x height` bitmap. Version 1.22.0 patches
 the issue. (CVE-2026-47714)

Solution

Update the libheif library and its related packages to version 1.19.8-1+e6 or later.
