CVE-2010-1163: Todd miller sudo improper input validation vulnerability

Todd Miller · Sudo

The command matching functionality in sudo 1.6.8 through 1.7.2p5 does not properly handle when a file in the current working directory has the same name as a pseudo-command in the sudoers file and the PATH contains an entry for ".", which allows local users to execute arbitrary commands via a Trojan horse executable, as demonstrated using sudoedit, a different vulnerability than CVE-2010-0426.
