RHEL 4 / 5 : pidgin (RHSA-2009:1453)
medium Nessus Plugin ID 41032
Synopsis
The remote Red Hat host is missing one or more security updates.Description
Updated pidgin packages that fix several security issues are now available for Red Hat Enterprise Linux 4 and 5.This update has been rated as having moderate security impact by the Red Hat Security Response Team.
Pidgin is an instant messaging program which can log in to multiple accounts on multiple instant messaging networks simultaneously.
Info/Query (IQ) is an Extensible Messaging and Presence Protocol (XMPP) specific request-response mechanism.
A NULL pointer dereference flaw was found in the way the Pidgin XMPP protocol plug-in processes IQ error responses when trying to fetch a custom smiley. A remote client could send a specially crafted IQ error response that would crash Pidgin. (CVE-2009-3085)
A NULL pointer dereference flaw was found in the way the Pidgin IRC protocol plug-in handles IRC topics. A malicious IRC server could send a specially crafted IRC TOPIC message, which once received by Pidgin, would lead to a denial of service (Pidgin crash). (CVE-2009-2703)
It was discovered that, when connecting to certain, very old Jabber servers via XMPP, Pidgin may ignore the 'Require SSL/TLS' setting. In these situations, a non-encrypted connection is established rather than the connection failing, causing the user to believe they are using an encrypted connection when they are not, leading to sensitive information disclosure (session sniffing). (CVE-2009-3026)
A NULL pointer dereference flaw was found in the way the Pidgin MSN protocol plug-in handles improper MSNSLP invitations. A remote attacker could send a specially crafted MSNSLP invitation request, which once accepted by a valid Pidgin user, would lead to a denial of service (Pidgin crash). (CVE-2009-3083)
These packages upgrade Pidgin to version 2.6.2. Refer to the Pidgin release notes for a full list of changes:
