SUSE SLES15 Security Update : giflib (SUSE-SU-2023:1970-2)

high Nessus Plugin ID 174708

Language:

Synopsis

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

Description

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:1970-2 advisory.

- Heap-based buffer overflow in util/gif2rgb.c in gif2rgb in giflib 5.1.2 allows remote attackers to cause a denial of service (application crash) via the background color index in a GIF file. (CVE-2016-3977)

- 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)

- In GIFLIB before 2019-02-16, a malformed GIF file triggers a divide-by-zero exception in the decoder function DGifSlurp in dgif_lib.c if the height field of the ImageSize data structure is equal to zero.
(CVE-2019-15133)

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

Solution

Update the affected giflib-devel and / or libgif7 packages.
