Subject: Re: LM an NTLM combination
I can reproduce the bug with the -4 version. Very intersting bug.
In version 5 i agregate this test in function cmp_one:
344 if(b!=t[1])
345 return 0;
This was because i try blocks of passwords and need a more especific test
(cmp_all could return 1 because only 1 password).
Puting this test in the 4 version fixed the bug. Why this occur? I really
dont know.
I think (-4 version) that before enter to cmp_one john need to enter to
cmp_all and checks the same condition that would make this checks (344,345)
innecesary.
But forget about cmp_all. Insert the lines in -4 patch. Eliminate this lines
(344,345) now could make that at least more or equal hashes pass the test of
cmp_one and the bug (if existed) need to be accept password that dont have
the current hash. But what happens its the opposite. And i dont understand
why in 2 pass john find passwords. Maybe Solar, who know the intrinsics of
john, can explain. I dont undestand.
