Medium Nessus Plugin ID 66670
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionIt was discovered that Tomcat incorrectly handled certain requests submitted using chunked transfer encoding. A remote attacker could use this flaw to cause the Tomcat server to stop responding, resulting in a denial of service. This issue only affected Ubuntu 10.04 LTS and Ubuntu 12.04 LTS. (CVE-2012-3544)
It was discovered that Tomcat incorrectly handled certain authentication requests. A remote attacker could possibly use this flaw to inject a request that would get executed with a victim's credentials. This issue only affected Ubuntu 10.04 LTS, Ubuntu 12.04 LTS, and Ubuntu 12.10. (CVE-2013-2067)
It was discovered that Tomcat sometimes exposed elements of a previous request to the current request. This could allow a remote attacker to possibly obtain sensitive information. This issue only affected Ubuntu 12.10 and Ubuntu 13.04. (CVE-2013-2071).
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.
