Description
This security bulletin contains information about 1 security vulnerability.
1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2012-2337)
The vulnerability allows a local non-authenticated attacker to execute arbitrary code.
sudo 1.6.x and 1.7.x before 1.7.9p1, and 1.8.x before 1.8.4p5, does not properly support configurations that use a netmask syntax, which allows local users to bypass intended command restrictions in opportunistic circumstances by executing a command on a host that has an IPv4 address.
Remediation
