New! Plugin Severity Now Using CVSS v3

Synopsis

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

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.

Solution

Upgrade the sudo packages.

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