    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.
