Ubuntu Security Notice (C) 2011-2016 Canonical, Inc. / NASL script (C) 2011-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

It was discovered that Tomcat incorrectly implemented HTTP DIGEST
authentication. An attacker could use this flaw to perform a variety
of authentication attacks. (CVE-2011-1184)

Polina Genova discovered that Tomcat incorrectly created log entries
with passwords when encountering errors during JMX user creation. A
local attacker could possibly use this flaw to obtain sensitive
information. This issue only affected Ubuntu 10.04 LTS, 10.10 and
11.04. (CVE-2011-2204)

It was discovered that Tomcat incorrectly validated certain request
attributes when sendfile is enabled. A local attacker could bypass
intended restrictions, or cause the JVM to crash, resulting in a
denial of service. (CVE-2011-2526)

It was discovered that Tomcat incorrectly handled certain AJP
requests. A remote attacker could use this flaw to spoof requests,
bypass authentication, and obtain sensitive information. This issue
only affected Ubuntu 10.04 LTS, 10.10 and 11.04. (CVE-2011-3190).

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 libtomcat6-java package.
