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

Ubuntu Security Notice (C) 2010-2017 Canonical, Inc. / NASL script (C) 2010-2017 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.

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.

Risk factor :

Medium / CVSS Base Score : 6.8
(CVSS2#AV:N/AC:M/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 5.6
(CVSS2#E:F/RL:OF/RC:ND)
