3. Description:
Pidgin is an instant messaging program which can log in to multiple
accounts on multiple instant messaging networks simultaneously.
An input sanitization flaw was found in the way the Pidgin SILC (Secure
Internet Live Conferencing) protocol plug-in escaped certain UTF-8
characters. A remote attacker could use this flaw to crash Pidgin via a
specially-crafted SILC message. (CVE-2011-3594)
Multiple NULL pointer dereference flaws were found in the way the Pidgin
Yahoo! Messenger Protocol plug-in handled malformed YMSG packets. A remote
attacker could use these flaws to crash Pidgin via a specially-crafted
notification message. (CVE-2011-1091)
Red Hat would like to thank the Pidgin project for reporting CVE-2011-1091.
Upstream acknowledges Marius Wachtler as the original reporter of
CVE-2011-1091.
All Pidgin users should upgrade to these updated packages, which contain
backported patches to resolve these issues. Pidgin must be restarted for
this update to take effect.
4. Solution:
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/kb/docs/DOC-11259
