|Title:||Ubuntu USN-142-1 (sudo)|
|Summary:||Ubuntu USN-142-1 (sudo)|
The remote host is missing an update to sudo
announced via advisory USN-142-1.
A security issue affects the following Ubuntu releases:
Ubuntu 4.10 (Warty Warthog)
Ubuntu 5.04 (Hoary Hedgehog)
The following packages are affected: sudo
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.
The problem can be corrected by upgrading the affected package to
version 1.6.7p5-1ubuntu4.2 (for Ubuntu 4.10), or 1.6.8p5-1ubuntu2.1
(for Ubuntu 5.04). In general, a standard system upgrade is
sufficient to effect the necessary changes.
