How to fix?

Upgrade Centos:6 pidgin to version 0:2.7.9-27.el6 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream pidgin package and not the pidgin package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

The XMPP protocol plugin in libpurple in Pidgin before 2.10.8 does not properly determine whether the from address in an iq reply is consistent with the to address in an iq request, which allows remote attackers to spoof iq traffic or cause a denial of service (NULL pointer dereference and application crash) via a crafted reply.
