Ubuntu 10.04 LTS / 11.04 : jetty vulnerability (USN-1429-1)

Medium Nessus Plugin ID 58892


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


It was discovered that Jetty computed hash values for form parameters without restricting the ability to trigger hash collisions predictably. This could allow a remote attacker to cause a denial of service by sending many crafted parameters.

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 libjetty-java package.
