I am sorry if it was rehashed before. I am running Linux/sparc, gcc 2.7.2.3.
The following patch fixes a memory corruption and crash:
Index: drivers/char/random.c
diff -u -r1.39 random.c
--- drivers/char/random.c 1999/09/01 08:04:15 1.39

if (!rekey_time || (tv.tv_sec - rekey_time) > REKEY_INTERVAL) {
rekey_time = tv.tv_sec;
/* First three words are overwritten below. */
- get_random_bytes(&secret+3, sizeof(secret)-12);
+ get_random_bytes(&secret[3], sizeof(secret)-12);
count = (tv.tv_sec/REKEY_INTERVAL) << HASH_BITS;
}
I cannot believe nobody hit it before, I must have missed a linux-kernel
thread. &secret+3 produces a pointer at three sizes of the array away
and way over the array boundaries.
