Ubuntu 10.04 LTS / 11.10 / 12.04 LTS : tomcat6 vulnerabilities (USN-1637-1)

Medium Nessus Plugin ID 63024


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


It was discovered that the Apache Tomcat HTTP NIO connector incorrectly handled header data. A remote attacker could cause a denial of service by sending requests with a large amount of header data. (CVE-2012-2733)

It was discovered that Apache Tomcat incorrectly handled DIGEST authentication. A remote attacker could possibly use these flaws to perform a replay attack and bypass authentication. (CVE-2012-5885, CVE-2012-5886, CVE-2012-5887).

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.


Update the affected libtomcat6-java package.
