Linux 2.2.X local exploit - A new local bug in the 2.2 kernel has been discovered. Using the "capabilities" bug, it is possable to exec sendmail without the CAP_SETUID priv, which makes the setuid() call which drops privileges fail. Large chunks of code which were never meant to run as root do, exploiting this is trivial. Working exploit for sendmail + 2.2.16pre5 and below is included.
