"A denial of service flaw was found in the Pidgin OSCAR protocol
implementation. If a remote ICQ user sent a web message to a local
Pidgin user using this protocol, it would cause excessive memory
usage, leading to a denial of service (Pidgin crash). (CVE-2009-1889)

These updated packages also fix the following bug :

  - the Yahoo! Messenger Protocol changed, making it
    incompatible (and unusable) with Pidgin versions prior
    to 2.5.7. This update provides Pidgin 2.5.8, which
    implements version 16 of the Yahoo! Messenger Protocol,
    which resolves this issue.

Note: These packages upgrade Pidgin to version 2.5.8.

Pidgin must be restarted for this update to take effect."
