high Tenable Cloud Security Plugin ID 455606

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 over-read in HeifPixelImage::overlay() in libheif/pixelimage.cc. When compositing an overlay image
 (iovl) whose child image has a different bit depth for the alpha channel than for the color channels, the
 function indexes into the alpha plane using the color channel stride (in_stride) instead of the previously
 retrieved alpha_stride, causing reads past the end of the alpha buffer (up to 3,123 bytes for a 100×50
 image with 10-bit color and 8-bit alpha). A crafted HEIF file can exploit this to cause a denial of
 service (crash) or potentially disclose adjacent heap memory through leaked bytes embedded in the decoded
 output pixels. This issue has been fixed in versionThis issue has been fixed in version 1.22.0.
 (CVE-2026-32882)
