Problem description

When sudo sends an email to the sysadmin about an unsuccessful effort to gain elevated privileges, users were able to pass environment variables along with the execve() system call when sendmail is called. The call for sendmail happens as root, which allows a local attacker to gain root privileges if sudo is installed with setuid-root permissions. The update package corrects this error by running sendmail not as root any more.

Solution

Please install the updates provided at the location noted below.
