Synopsis
The remote Scientific Linux host is missing one or more security updates.Description
CVE-2009-3026 pidgin: ignores SSL/TLS requirements with old jabber serversCVE-2009-2703 Pidgin: NULL pointer dereference by handling IRC topic(s) (DoS)
CVE-2009-3083 Pidgin: NULL pointer dereference by processing incomplete MSN SLP invite (DoS)
CVE-2009-3085 Pidgin: NULL pointer dereference by processing a custom smiley (DoS)
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)
Pidgin must be restarted for this update to take effect.
