OpenSSL < 0.9.8r / 1.0.0d OCSP Stapling Denial of Service

medium Log Correlation Engine Plugin ID 801053

Synopsis

The remote web server is vulnerable to multiple attack vectors.

Description

Versions of OpenSSL earlier than 0.9.8r and 1.0.0d are potentially affected by a vulnerability wherein an incorrectly formatted ClientHello handshake message could cause OpenSSL to parse past the end of the message which could cause the web server to crash. There is also the potential for information disclosure if OCSP nonce extensions are used.

Solution

Upgrade to OpenSSL 0.9.8r, 1.0.0d, or later.
