libgd2 - security update

Multiple vulnerabilities were discovered in libgd2, a graphics library:

• CVE-2014-2497
  The gdImageCreateFromXpm() function would try to dereference a NULL
  pointer when reading an XPM file with a special color table. This
  could allow remote attackers to cause a denial of service (crash) via
  crafted XPM files.
• CVE-2014-9709
  Importing an invalid GIF file using the gdImageCreateFromGif() function
  would cause a read buffer overflow that could allow remote attackers to
  cause a denial of service (crash) via crafted GIF files.

For the stable distribution (wheezy), these problems have been fixed in
version 2.0.36~rc1~dfsg-6.1+deb7u1.

For the upcoming stable distribution (jessie), these problems have been
fixed in version 2.1.0-5.

For the unstable distribution (sid), these problems have been fixed in
version 2.1.0-5.

We recommend that you upgrade your libgd2 packages.
