Scientific Linux Security Update : pidgin on SL4.x, SL5.x i386/x86_64
Medium Nessus Plugin ID 60876
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionMultiple 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)
Pidgin must be restarted for this update to take effect.
SolutionUpdate the affected packages.
