The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - libheif is a HEIF and AVIF file format decoder and encoder. In 1.23.0 and earlier, a crafted HEIF or AVIF     file containing a clean aperture box can reduce an image dimension to zero and crash or corrupt tiling     results when heif_image_handle_get_image_tiling(handle, 1, &tiling) is called.
    ImageItem::get_heif_image_tiling() returns already transformed dimensions, and     process_image_transformations_on_tiling() applies the clean aperture transformation again. The second     application passes zero to Box_clap::left_rounded(0), where image_width minus one underflows and     constructs Fraction(0xFFFFFFFF, 2). Debug builds reach an assertion and abort, while release builds can     return a corrupt crop and zero-width tiling result. The affected implementation spans libheif/image-     items/image_item.cc, libheif/context.cc, and libheif/box.cc. This issue is fixed in version 1.23.1.
    (CVE-2026-62289)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:21644-1 advisory.

    Update to version 1.23.1 (jsc#PED-16355).

    Security issues fixed:

    - CVE-2026-62289: integer underflow in Fraction constructor via double clap transform application     (bsc#1273079).
    - CVE-2026-62291: heap out-of-bounds write in the uncompressed encoder when writing images with mismatched     auxiliary       alpha dimensions (bsc#1273080).
    - CVE-2026-62292: out-of-bounds read in uncompressed unci tile range slicing (bsc#1273081).
    - CVE-2026-62377: reachable assertion in `HeifContext::get_track()` aborts on a valid-but-empty HEIF     sequence file       (bsc#1273082).
    - Heap out-of-bounds write in the uncompressed encoder for RRGGBB images with interleaved bit-depth `<= 8`       (bsc#1273083).

    Changes for libheif:

    - Version 1.23.1
      - FFmpeg decoder plugin gains AV1, VVC, JPEG, and JPEG 2000/HTJ2K decoding.
      - SVT-AV1 encoder: new `tune=iq` and `ms-ssim` tune parameters.
      - C++ API: added getters/setters for the CLLI and MDCV HDR metadata boxes.
      - Sequence decoder now scales the alpha auxiliary track to the main image size.
      - Fixed pixi box writing for multi-channel images.
      - Corrected the placement of the TAI `clock_type` field into the top 2 bits.
      - Empty/unset plugin directory is no longer scanned.

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

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

The remote Debian 13 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6417 advisory.

    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.
