"An integer overflow flaw was found in Pidgin's MSN protocol handler.
If a user received a malicious MSN message, it was possible to execute
arbitrary code with the permissions of the user running Pidgin.
(CVE-2008-2927)

Note: the default Pidgin privacy setting only allows messages from
users in the buddy list. This prevents arbitrary MSN users from
exploiting this flaw.

This update also addresses the following bug :

  - when attempting to connect to the ICQ network, Pidgin
    would fail to connect, present an alert saying the 'The
    client version you are using is too old', and
    de-activate the ICQ account. This update restores
    Pidgin's ability to connect to the ICQ network."
