Ubuntu 12.04 LTS : tomcat6 vulnerabilities (USN-2655-1)

Ubuntu Security Notice (C) 2015-2016 Canonical, Inc. / NASL script (C) 2015-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

It was discovered that Tomcat incorrectly handled data with malformed
chunked transfer coding. A remote attacker could possibly use this
issue to conduct HTTP request smuggling attacks, or cause Tomcat to
consume resources, resulting in a denial of service. (CVE-2014-0227)

It was discovered that Tomcat incorrectly handled HTTP responses
occurring before the entire request body was finished being read. A
remote attacker could possibly use this issue to cause memory
consumption, resulting in a denial of service. (CVE-2014-0230)

It was discovered that the Tomcat Expression Language (EL)
implementation incorrectly handled accessible interfaces implemented
by inaccessible classes. An attacker could possibly use this issue to
bypass a SecurityManager protection mechanism. (CVE-2014-7810).

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.
