New versions of the OpenSSL library were recently released to patch a denial of service vulnerability that was introduced by a January 6 update.

"'A flaw in the fix to CVE-2011-4108 can be exploited in a denial of service attack,' the OpenSSL developers warned in a newly published advisory," writes PCWorld's Lucian Constantin. "The issue has been addressed in the new OpenSSL 1.0.0g and 0.9.8t versions released on Wednesday."

"CVE-2011-4108 refers to a serious vulnerability in OpenSSL's implementation of the DTLS (Datagram Transport Layer Security) protocol, which allows attackers to decrypt secured communications without knowing the encryption key," Constantin writes.
