A vulnerability has been reported in Sudo, which can be exploited by malicious users to bypass certain security restrictions.
The vulnerability is caused due to an error within the network matching mechanism when processing hosts based on the IPv4 netmask. This can be exploited to execute commands from otherwise restricted hosts.
Successful exploitation requires that the user exists in the sudoers file and is granted access to commands on hosts on one or more IPv4 networks.
The vulnerability is reported in versions 1.6.9p3 through 1.8.4p4.
Solution: Update to version 1.8.4p5 or 1.7.9p1.
