Several vulnerabilities have been discovered in sudo, a program designed to allow a sysadmin to give limited root privileges to users. The Common Vulnerabilities and Exposures project identifies the following problems:
Marco Schoepl discovered an authentication bypass when the clock is set to the UNIX epoch [00:00:00 UTC on 1 January 1970].
Ryan Castellucci and James Ogden discovered aspects of an issue that would allow session id hijacking from another authorized tty.
For the stable distribution (squeeze), these problems have been fixed in version 1.7.4p4-2.squeeze.4.
For the testing (wheezy) and unstable (sid) distributions, these problems have been fixed in version 1.8.5p2-1+nmu1.
We recommend that you upgrade your sudo packages.
