A weakness has been reported in Pidgin, which can be exploited by malicious people to cause a DoS (Denial of Service).
The weakness is caused due to insufficient input validation in libpurple's MSN protocol plugin when processing SLP packets related to custom emoticons. This can be exploited to crash the application via a specially crafted SLP message.
Solution: Update to version 2.7.0.
