pidgin - remote code execution

Ulf Härnhammar found a buffer overflow in Pidgin, a multi protocol instant
messaging client. The vulnerability can be exploited by an incoming
message in the MXit protocol plugin. A remote attacker may cause a crash,
and in some circumstances can lead to remote code execution.

For the stable distribution (squeeze), this problem has been fixed in
version 2.7.3-1+squeeze3.

For the unstable distribution (sid), this problem has been fixed in

We recommend that you upgrade your pidgin packages.
