USN-1429-1: Jetty vulnerability

26 April 2012

Jetty could be made to hang or crash if it received specially crafted network traffic.



  • jetty - Java servlet engine and webserver


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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 11.04
Ubuntu 10.04

In general, a standard system update will make all the necessary changes.
