Debian DSA-2642-1 : sudo - several issues

medium Nessus Plugin ID 65179
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Debian host is missing a security-related update.


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.


Upgrade the sudo packages.

For the stable distribution (squeeze), these problems have been fixed in version 1.7.4p4-2.squeeze.4.
