*) Changes in security patch:
Changes marked "(CHATS)" were sponsored by the Defense Advanced
Research Projects Agency (DARPA) and Air Force Research Laboratory,
Air Force Materiel Command, USAF, under agreement number
F30602-01-2-0537.
*) Add various sanity checks to asn1_get_length() to reject
the ASN1 length bytes if they exceed sizeof(long), will appear
negative or the content length exceeds the length of the
supplied buffer.
[Steve Henson, Adi Stav <stav@mercury.co.il>, James Yonan <jim@ntlp.com>]
*) Assertions for various potential buffer overflows, not known to
happen in practice.
[Ben Laurie (CHATS)]
*) Various temporary buffers to hold ASCII versions of integers were
too small for 64 bit platforms. (CAN-2002-0655)
[Matthew Byng-Maddick <mbm@aldigital.co.uk> and Ben Laurie (CHATS)>
*) Remote buffer overflow in SSL3 protocol - an attacker could
supply an oversized session ID to a client. (CAN-2002-0656)
[Ben Laurie (CHATS)]
*) Remote buffer overflow in SSL2 protocol - an attacker could
supply an oversized client master key. (CAN-2002-0656)
[Ben Laurie (CHATS)]
Changes between 0.9.6c and 0.9.6d [9 May 2002]
*) Fix crypto/asn1/a_sign.c so that 'parameters' is omitted (not
