Common Vulnerabilities and Exposures assigned an identifier CVE-2013-6450 to the following vulnerability: The DTLS retransmission implementation in OpenSSL through 0.9.8y and 1.x through 1.0.1e does not properly maintain data structures for digest and encryption contexts, which might allow man-in-the-middle attackers to trigger the use of a different context by interfering with packet delivery, related to ssl/d1_both.c and ssl/t1_enc.c.

OpenSSL 0.9.8 is not affected.
Issue was fixed in upstream version 1.0.1f and 1.0.0l: http://www.openssl.org/news/vulnerabilities.html#2013-6450 http://www.openssl.org/news/openssl-1.0.1-notes.html http://www.openssl.org/news/openssl-1.0.0-notes.html
DTLS protocol support is not available in openssl packages in Red Hat Enterprise Linux 4 and earlier. Red Hat Enterprise Linux 5 uses openssl 0.9.8, which is not affected (see comment 7). Statement: This issue did not affect the versions of openssl as shipped with Red Hat Enterprise Linux 5 and earlier.
This issue has been addressed in following products: Red Hat Enterprise Linux 6 Via RHSA-2014:0015 https://rhn.redhat.com/errata/RHSA-2014-0015.html

SUSE was reporting [1] some crashes with a patched openssl, so I wanted to clarify here that they were missing part of the required fix. In addition to the upstream commit noted in comment #0: http://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=3462896 Upstream also indicated [2] that this patch was required: http://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=a6c62f0 We have this patch in our openssl-1.0.1e-cve-2013-6450.patch which was applied to Red Hat Enterprise Linux 6's fix, as noted above. So the problems that SUSE was describing would not affect Red Hat Enterprise Linux 6.
