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?
