Debian DSA-2006-1 : sudo - several vulnerabilities

Medium Nessus Plugin ID 44970

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-2010-0426 It was discovered that sudo when a pseudo-command is enabled, permits a match between the name of the pseudo-command and the name of an executable file in an arbitrary directory, which allows local users to gain privileges via a crafted executable file.

- CVE-2010-0427 It was discovered that sudo when the runas_default option is used, does not properly set group memberships, which allows local users to gain privileges via a sudo command.

Solution

Upgrade the sudo package.

For the stable distribution (lenny), these problems have been fixed in version 1.6.9p17-2+lenny1
