Debian Security Advisory DSA-3938-1 [email protected]
https://www.debian.org/security/ Salvatore Bonaccorso

Package : libgd2
CVE ID : CVE-2017-7890
Debian Bug : 869263

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 the oldstable distribution (jessie), this problem has been fixed
in version 2.1.0-5+deb8u10.

For the stable distribution (stretch), this problem has been fixed in
version 2.2.4-2+deb9u1.

We recommend that you upgrade your libgd2 packages.
