Debian Security Advisory

DLA-1055-1 libgd2 -- LTS security update

Date Reported:
12 Aug 2017
Affected Packages:
Security database references:
In Mitre's CVE dictionary: CVE-2017-7890.
More information:

Matviy Kotoniy reported that the gdImageCreateFromGifCtx() function used to load images from GIF format files in libgd2, a library for programmatic graphics creation and manipulation, does not zero stack allocated color map buffers before their use, which may result in information disclosure if a specially crafted file is processed.

For Debian 7 Wheezy, these problems have been fixed in version 2.0.36~rc1~dfsg-6.1+deb7u9.

We recommend that you upgrade your libgd2 packages.
