OpenSSL Project OpenSSL prior to 1.0.0m
OpenSSL Project OpenSSL prior to 0.9.8za
A security bypass via ChangeCipherSpec (CCS) Injection vulnerability has been reported in older versions of OpenSSL. The vulnerability is due to a weakness in OpenSSL methods used for keying material. The vulnerability can be exploited through the use of a man in the middle attack, where an attacker may be able to decrypt and modify traffic in transit. A remote unauthenticated attacker could exploit this vulnerability by using a specially crafted handshake to force the use of weak keying material.
This protection will detect and block attempts to exploit this vulnerability.
In order for the protection to be activated, update your Security Gateway product to the latest IPS update. For information on how to update IPS, go to SBP-2006-05, Protection tab and select the version of your choice.
