Synopsis

The remote openSUSE host is missing one or more security updates.

Description

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.

Solution
