Debian DLA-3223-1 : giflib - LTS security update

high Nessus Plugin ID 168399

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3223 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)

- 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

Upgrade the giflib packages.

For Debian 10 buster, these problems have been fixed in version 5.1.4-3+deb10u1.
