Ubuntu 9.04 / 9.10 / 10.04 LTS : tomcat6 vulnerability (USN-976-1)

Medium Nessus Plugin ID 48757


The remote Ubuntu host is missing one or more security-related patches.


It was discovered that Tomcat incorrectly handled invalid Transfer-Encoding headers. A remote attacker could send specially crafted requests containing invalid headers to the server and cause a denial of service, or possibly obtain sensitive information from other requests.

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 packages.
