OpenSSL J-PAKE security bypass
|openssl-jpake-security-bypass (63636)||Medium Risk|
OpenSSL could allow a remote attacker to bypass security restrictions, caused by an error in the J-PAKE implementation. A remote attacker could exploit this vulnerability to authenticate without the shared secret.
Upgrade to the latest version of OpenSSL (1.0.0c or later), available from the OpenSSL Web site. See References.
For other distributions:
Apply the appropriate update for your system. See References.
