Package : libheif CVE ID : CVE-2025-68431 CVE-2026-32740 CVE-2026-32741 CVE-2026-32882 CVE-2026-47178 CVE-2026-47247 CVE-2026-47709 CVE-2026-47714 CVE-2026-48029 CVE-2026-49271 CVE-2026-62289 CVE-2026-62292 Debian Bug :

Multiple security issues were discovered in libheif, an ISO/IEC 23008-12 HEIF and AVIF image file format decoder and encoder, which may result in denial of service, the disclosure of sensitive memory contents or, potentially, the execution of arbitrary code if a malformed image file is processed.

Note that in the fix for CVE-2026-47178, a heap out-of-bounds write in the uncompressed tile decoder, the affected format combinations are now rejected with heif_error_Unsupported_feature: uncompressed images with 4:2:0 or 4:2:2 chroma subsampling that are tiled, or that use row or pixel interleave.
Upstream corrected the offending arithmetic, but only after a restructuring of the uncompressed decoder that is not present in the version shipped in the stable distribution. Images in these configurations will no longer decode.

For the stable distribution (trixie), these problems have been fixed in version 1.19.8-1+deb13u1.

We recommend that you upgrade your libheif packages.

For the detailed security status of libheif please refer to its security tracker page at:

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the heif-gdk-pixbuf packages.
