Ubuntu 12.04 LTS : tomcat6 vulnerabilities (USN-2655-1)
High Nessus Plugin ID 84430
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionIt 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.
SolutionUpdate the affected libtomcat6-java package.
