Phillip Hallam-Baker discovered that window property values could be queried in rxvt-unicode, resulting in the potential execution of arbitrary commands.

For the oldstable distribution (squeeze), this problem has been fixed in version 9.07-2+deb6u1. For the stable distribution (wheezy), this problem has been fixed in version 9.15-2+deb7u1. For the testing distribution (jessie), this problem has been fixed in version 9.20-1. For the unstable distribution (sid), this problem has been fixed in version 9.20-1. We recommend that you upgrade your rxvt-unicode packages.

rxvt-unicode is a modern, Unicode-aware color xterm replacement that uses significantly less memory than a conventional xterm and many other Unicode supporting terminal emulators.
