24th January, 2011

tomcat6 vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 10.10
  • Ubuntu 10.04 LTS
  • Ubuntu 9.10

Software description

  • tomcat6

Details

It was discovered that Tomcat did not properly escape certain parameters in
the Manager application which could result in browsers becoming vulnerable
to cross-site scripting attacks when processing the output. With cross-site
scripting vulnerabilities, if a user were tricked into viewing server
output during a crafted server request, a remote attacker could exploit
this to modify the contents, or steal confidential data (such as
passwords), within the same domain.

Update instructions

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

Ubuntu 10.10:
tomcat6-admin 6.0.28-2ubuntu1.1
Ubuntu 10.04 LTS:
tomcat6-admin 6.0.24-2ubuntu1.6
Ubuntu 9.10:
tomcat6-admin 6.0.20-2ubuntu2.3

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.

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