sudo vulnerability

Releases

• Ubuntu 5.04
• Ubuntu 4.10

Details

Charles Morris discovered a race condition in sudo which could lead to
privilege escalation. If /etc/sudoers allowed a user the execution of
selected programs, and this was followed by another line containing
the pseudo-command “ALL”, that user could execute arbitrary commands
with sudo by creating symbolic links at a certain time.

Please note that this does not affect a standard Ubuntu installation.
