Package : giflib Version : 5.1.4-3+deb10u1 CVE ID : CVE-2018-11490 CVE-2019-15133 Debian Bug : 904114

This update fixes two file format vulnerabilities in giflib.

CVE-2018-11490

The DGifDecompressLine function in dgif_lib.c, 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-2019-15133

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.

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

We recommend that you upgrade your giflib packages.
