Security patch for OpenSSL Vulnerability

  1. OpenSSL vulnerability that allows a potential timing-based attack and a modified
    Bleichenbacher attack. 

    The SSL and TLS components for OpenSSL 0.9.6i and earlier, 0.9.7, and 0.9.7a 
    allow remote attackers to perform an unauthorized RSA private key operation via 
    a modified Bleichenbacher attack that uses a large number of SSL or TLS connections 
    using PKCS #1 v1.5 padding that cause OpenSSL to leak information regarding the 
    relationship between ciphertext and the associated plaintext, aka the 
    "Klima-Pokorny-Rosa attack." 

    Advisory details for the security patch are available at the following URL: 

Other Resolved Issues :

  • After upgrading the existing WEBppliance 3.1.x server, domain preview using 
    http://servername/domainname/ was broken. This problem is corrected in 
    WEBppliance 3.1.10.
