Details

Valerio Costamagna discovered that sudo did not properly validate the path
for the ‘sudoedit’ pseudo-command when the PATH contained only a dot (‘.’).
If secure_path and ignore_dot were disabled, a local attacker could exploit
this to execute arbitrary code as root if sudo was configured to allow the
attacker to use sudoedit. By default, secure_path is used and the sudoedit
pseudo-command is not used in Ubuntu. This is a different but related issue
to CVE-2010-0426.
