CVE-2010-1163
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.");
