Summary:	The remote host is missing an update for the 'irssi' package(s) announced via the USN-929-2 advisory.
Description:	Summary: The remote host is missing an update for the 'irssi' package(s) announced via the USN-929-2 advisory. Vulnerability Insight: USN-929-1 fixed vulnerabilities in irssi. The upstream changes introduced a regression when using irssi with SSL and an IRC proxy. This update fixes the problem. We apologize for the inconvenience. Original advisory details: It was discovered that irssi did not perform certificate host validation when using SSL connections. An attacker could exploit this to perform a man in the middle attack to view sensitive information or alter encrypted communications. (CVE-2010-1155) Aurelien Delaitre discovered that irssi could be made to dereference a NULL pointer when a user left the channel. A remote attacker could cause a denial of service via application crash. (CVE-2010-1156) This update also adds SSLv3 and TLSv1 support, while disabling the old, insecure SSLv2 protocol. Affected Software/OS: 'irssi' package(s) on Ubuntu 8.04, Ubuntu 8.10, Ubuntu 9.04, Ubuntu 9.10. Solution: Please install the updated package(s). CVSS Score: 6.8 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:P/A:P
