Ubuntu 11.04 : rsyslog vulnerability (USN-1338-1)

Ubuntu Security Notice (C) 2012-2013 Canonical, Inc. / NASL script (C) 2012-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

Peter Eisentraut discovered that Rsyslog would not properly perform
input validation when configured to use imfile. If an attacker were
able to craft messages in a file that Rsyslog monitored, an attacker
could cause a denial of service. The imfile module is disabled by
default in Ubuntu.

Solution :

Update the affected rsyslog package.

Risk factor :

Low / CVSS Base Score : 2.1
(CVSS2#AV:L/AC:L/Au:N/C:N/I:N/A:P)
