@ -8,6 +8,10 @@ Changes
Security
* Avoid potential timing leak in ecdsa_sign() by blinding modular division.
(Found by Watson Ladd.)
* The notAfter date of some certificates was no longer checked since 1.3.5.
This affects certificates in the user-supplied chain except the top
certificate. If the user-supplied chain contains only one certificates,
it is not affected (ie, its notAfter date is properly checked).
Bugfix
* The length of various ClientKeyExchange messages was not properly checked.
