SUSE SLES12 Security Update : giflib (SUSE-SU-2024:1622-1)

high Nessus Plugin ID 196941



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


The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:1622-1 advisory.

- The DGifDecompressLine function in dgif_lib.c in GIFLIB (possibly version 3.0.x), as later shipped in cgif.c in sam2p 0.49.4, has a heap-based buffer overflow because a certain Private->RunningCode - 2 array index is not checked. This will lead to a denial of service or possibly unspecified other impact.

- A memory leak (out-of-memory) in gif2rgb in util/gif2rgb.c in giflib 5.1.4 allows remote attackers trigger an out of memory exception or denial of service via a gif format file. (CVE-2021-40633)

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


Update the affected giflib-devel, giflib-progs, libgif6 and / or libgif6-32bit packages.
