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.
