Ubuntu Security Notice USN-703-1 January 06, 2009 xterm vulnerability
CVE-2006-7236, CVE-2008-2383

A security issue affects the following Ubuntu releases: Ubuntu 6.06 LTS Ubuntu 7.10 Ubuntu 8.04 LTS Ubuntu 8.10

This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu.

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

Ubuntu 6.06 LTS: xterm 208-3.1ubuntu3.1 Ubuntu 7.10: xterm 229-1ubuntu0.1 Ubuntu 8.04 LTS: xterm 229-1ubuntu1.1 Ubuntu 8.10: xterm 235-1ubuntu1.1

After a standard system upgrade you need to restart any running xterms to effect the necessary changes.

Details follow:

Paul Szabo discovered that the DECRQSS escape sequences were not handled correctly by xterm. Additionally, window title operations were also not safely handled. If a user were tricked into viewing a specially crafted series of characters while in xterm, a remote attacker could execute arbitrary commands with user privileges. (CVE-2006-7236, CVE-2008-2382)
