Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:4276-1 advisory.

- CVE-2026-84383: Heap buffer overflow in scale_nearest_neighbor() via duplicate alpha planes from nested iden/auxl items (bsc#1279443).
- CVE-2026-84384: brotli/zlib decompression paths lack output-size limits, allowing decompression-bomb OOM/DoS (bsc#1279445).
- CVE-2026-84444: Out-of-bounds write in the unci encoder (bsc#1279448).
- CVE-2026-84446: Sequence decode timing-table initialization allows non-terminating loops and unbounded memory, bypassing max_sequence_frames (bsc#1279447).
- CVE-2026-84447: Derived-image indirect reference chains and tiled offsets bypass decode caching and MemoryHandle limits, causing CPU/memory amplification DoS (bsc#1279446).
- CVE-2026-84448: Heap out-of-bounds read in the inline-mask region API (bsc#1279449).
- CVE-2026-84450: image item with `clap` property and an ispe declaring a dimension greater than `INT32_MAX + 1` can lead to a crash via an abort (bsc#1280002).
- CVE-2026-84451: crafted HEIF file advertising a 4096 x 4096 uncompressed tile grid can cause an out-of- bounds read due to an integer overflow (bsc#1280001).
- Out-of-bounds read and write in derived-item and pixel-plane handling (bsc#1279444).
