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.

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 23.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6824-1 advisory.

    It was discovered that GIFLIB incorrectly handled certain GIF files. An attacker could possibly use this     issue to cause a denial of service. (CVE-2021-40633, CVE-2022-28506, CVE-2023-39742)

Tenable has extracted the preceding description block directly from the Ubuntu 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 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.
    (CVE-2018-11490)

  - 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)
