Description Tomas Hoger 2013-12-20 04:28:44 EST
A flaw was reported for OpenSSL 1.0.1e, that can cause application using OpenSSL to crash when using TLS version 1.2.  Issue was reported via the following OpenSSL upstream ticket:

http://rt.openssl.org/Ticket/Display.html?id=3200&user=guest&pass=guest

and also as bug for Apache Traffic Server:

https://issues.apache.org/jira/browse/TS-2355

Fix is now committed in upstream git:

http://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=ca98926

Related to the above ticket, upstream also added this fix to improve error checks in OpenSSL:

Comment 1 Tomas Hoger 2013-12-20 07:23:52 EST
Support for TLS 1.2 in openssl packages in Red Hat Enterprise Linux 6 was only introduced in Red Hat Enterprise Linux 6.5, when openssl packages were updated from version 1.0.0 to 1.0.1e via RHBA-2013:1585.  The openssl packages in Red Hat Enterprise Linux 6 before 6.5 and earlier versions of Red Hat Enterprise Linux do not support TLS 1.1 and 1.2.
