Welcome to the zer0-day haulocaust.
-=[ Sendmail 8.13.5 and below Remote Signal Handling exploit Proof of Concept for the remote signal handling vulnerability by redsand
From the Sendmail release notes:
8.13.6/8.13.6 2006/03/22 SECURITY: Replace unsafe use of setjmp(3)/longjmp(3) in the server and client side of sendmail with timeouts in the libsm I/O layer and fix problems in that code. Also fix handling of a buffer in sm_syslog() which could have been used as an attack vector to exploit the unsafe handling of setjmp(3)/longjmp(3) in combination with signals. Problem detected by Mark Dowd of ISS X-Force. It's not much of a zero day when the fix shipped 4 months ago, now is it?
