Ubuntu 8.04 LTS / 8.10 / 9.04 / 9.10 : irssi vulnerabilities (USN-929-1)

medium Nessus Plugin ID 45551

Language:

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected irssi and / or irssi-dev packages.
