CentOS Errata and Security Advisory CESA-2010:0788
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 Nogues 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.
