Description

OpenSSL contains a flaw that may allow a remote denial of service. The issue is triggered when an error occurs while parsing malformed ClientHello handshake messages, which may be exploited to trigger an invalid memory access with a crafted ClientHello handshake message. This may allow a remote attacker to cause a denial of service. Certain applications which use SSL may also allow the disclosure of the contents of parsed OCSP extensions.
