Package : libgd2
Version : 2.0.36~rc1~dfsg-6.1+deb7u7
CVE ID : CVE-2016-9933
Debian Bug : 849038

It was discovered that invalid color causes stack exhaustion by
recursive call to function gdImageFillToBorder when the image used is
truecolor.

The vulnerability can be exploited through php5 which uses system's
libgd2 library through the imagefilltoborder() PHP function to cause
denial of service (stack overflow) and possibly have unspecified other
impact.

For Debian 7 "Wheezy", these problems have been fixed in version
2.0.36~rc1~dfsg-6.1+deb7u7.

We recommend that you upgrade your libgd2 packages.

these updates to your system and frequently asked questions can be
