Test ID:
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2009:1139
The remote host is missing updates announced in
advisory RHSA-2009:1139.

Pidgin is an instant messaging program which can log in to multiple
accounts on multiple instant messaging networks simultaneously. The AOL
Open System for CommunicAtion in Realtime (OSCAR) protocol is used by the
AOL ICQ and AIM instant messaging systems.

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. Refer to the Pidgin
release notes for a full list of changes:

All Pidgin users should upgrade to these updated packages, which correct
these issues. Pidgin must be restarted for this update to take effect.

Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
