Description

Package : libgd2 Version : 2.0.36~rc1~dfsg-6.1+deb7u9 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.
