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

Ubuntu Security Notice (C) 2012-2016 Canonical, Inc. / NASL script (C) 2012-2016 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.

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 rsyslog package.

Risk factor :

Low / CVSS Base Score : 2.1
(CVSS2#AV:L/AC:L/Au:N/C:N/I:N/A:P)
CVSS Temporal Score : 1.8
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : false
