Updated pidgin packages that fix multiple security issues are now
available for Red Hat Enterprise Linux 4 and 5.
The Red Hat Security Response Team has rated this update as having
moderate security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.
Pidgin is an instant messaging program which can log in to multiple
accounts on multiple instant messaging networks simultaneously.
Multiple NULL pointer dereference flaws were found in the way Pidgin
handled Base64 decoding. A remote attacker could use these flaws to
crash Pidgin if the target Pidgin user was using the Yahoo! Messenger
Protocol, MSN, MySpace, or Extensible Messaging and Presence Protocol
(XMPP) protocol plug-ins, or using the Microsoft NT LAN Manager (NTLM)
protocol for authentication. (CVE-2010-3711)
A NULL pointer dereference flaw was found in the way the Pidgin MSN
protocol plug-in processed custom emoticon messages. A remote attacker
could use this flaw to crash Pidgin by sending specially-crafted
emoticon messages during mutual communication. (CVE-2010-1624)
Red Hat would like to thank the Pidgin project for reporting these
issues. Upstream acknowledges Daniel Atallah as the original reporter
of CVE-2010-3711, and Pierre NoguÃ¨s of Meta Security as the original
reporter of CVE-2010-1624.
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.
