By supplying specially crafted packets a remote attacker can cause Tor to overflow its heap, crashing the process. Arbitrary code execution has not been confirmed but there is a potential risk. In the stable distribution (lenny), this update also includes an update of the IP address for the Tor directory authority gabelmoo and addresses a weakness in the package's postinst maintainer script. For the stable distribution (lenny) this problem has been fixed in version 0.2.1.26-1~lenny+4. For the testing distribution (squeeze) and the unstable distribution (sid), this problem has been fixed in version 0.2.1.26-6. We recommend that you upgrade your tor packages.
