Name of the Vulnerable Software and Affected Versions Pidgin versions prior to 2.6.2

Description The issue allows remote attackers to cause a denial of service, resulting in a NULL pointer dereference and application crash. This can be achieved through an SLP invite message lacking certain required fields. The vulnerability has been demonstrated with a malformed message from a KMess client. The issue affects the MSN protocol plugin in libpurple.

Recommendations For versions prior to 2.6.2, update to version 2.6.2 or later to resolve the issue. As a temporary workaround, consider restricting the handling of SLP invite messages to minimize the risk of exploitation.
