Description

sudo contains a flaw that may allow a malicious local user to manipulate arbitrary files on the system. The issue is due to the VIsudo creating temporary files insecurely if it is invoked on a sudoers file that is contained in a world writable directory. It is possible for a user to use a symlink style attack to corrupt arbitrary files, resulting in a loss of integrity.
