Squid NTLM Authenticate Overflow

This is an exploit for Squid\'s NTLM authenticate overflow (libntlmssp.c). Due to improper bounds checking in ntlm_check_auth, it is possible to overflow the 'pass' variable on the stack with user controlled data of a user defined length. Props to iDEFENSE for the advisory.
