(LiveHacking.Com) – Earlier this month, the OpenSSL project released updates to two new versions (OpenSSL 1.0.0f and 0.9.8s) of the popular open source toolkit for SSL/TLS to fix a total of six security flaws. One of the vulnerabilities fixed (CVE-2011-4108) was in OpenSSL’s DTLS implementation which allowed an efficient plaintext recovery attack. However Antonio Martin from Cisco Systems, Inc found a flaw in the in the fix that can be exploited in a denial of service attack. Only DTLS applications using OpenSSL 1.0.0f and 0.9.8s are affected.
To remedy this the OpenSSL project have now released OpenSSL 1.0.0g and OpenSSL 0.9.8t.
