Debian DSA-3556-1 : libgd2 - security update

critical Nessus Plugin ID 90688
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Debian host is missing a security-related update.


Hans Jerry Illikainen discovered that libgd2, a library for programmatic graphics creation and manipulation, suffers of a signedness vulnerability which may result in a heap overflow when processing specially crafted compressed gd2 data. A remote attacker can take advantage of this flaw to cause an application using the libgd2 library to crash, or potentially, to execute arbitrary code with the privileges of the user running the application.


Upgrade the libgd2 packages.

For the oldstable distribution (wheezy), this problem has been fixed in version 2.0.36~rc1~dfsg-6.1+deb7u2.

For the stable distribution (jessie), this problem has been fixed in version 2.1.0-5+deb8u1.
