RedHat: Important: pidgin security update RHSA-2009:1059-02
Summary
Pidgin is an instant messaging program which can log in to multiple
accounts on multiple instant messaging networks simultaneously.
A buffer overflow flaw was found in the way Pidgin initiates file transferswhen using the Extensible Messaging and Presence Protocol (XMPP). If a
Pidgin client initiates a file transfer, and the remote target sends a
malformed response, it could cause Pidgin to crash or, potentially, execute
arbitrary code with the permissions of the user running Pidgin. This flaw
only affects accounts using XMPP, such as Jabber and Google Talk.
(CVE-2009-1373)
It was discovered that on 32-bit platforms, the Red Hat Security Advisory
RHSA-2008:0584 provided an incomplete fix for the integer overflow flaw
affecting Pidgin's MSN protocol handler. If a Pidgin client receives a
specially-crafted MSN message, it may be possible to execute arbitrary code
with the permissions of the user running Pidgin. (CVE-2009-1376)
Note: By default, when using an MSN account, only users on your buddy list
can send you messages. This prevents arbitrary MSN users from exploiting
this flaw.
All Pidgin users should upgrade to this update package, which contains
backported patches to resolve these issues. Pidgin must be restarted for
this update to take effect.
