CVE ID         : CVE-2017-7890


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.
