Ubuntu Security Notice (C) 2010-2013 Canonical, Inc. / NASL script (C) 2010-2013 Tenable Network Security, Inc.


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.

Solution :

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

Risk factor :

Medium / CVSS Base Score : 6.8
(CVSS2#AV:N/AC:M/Au:N/C:P/I:P/A:P)
