Description

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:

CVE-2013-1775 Marco Schoepl discovered an authentication bypass when the clock is set to the UNIX epoch [00:00:00 UTC on 1 January 1970].

CVE-2013-1776 Ryan Castellucci and James Ogden discovered aspects of an issue that would allow session id hijacking from another authorized tty.
