Debian 10176 Published by

Updated libgd2 packages has been released for Debian 7 LTS



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.
