CWE-310  (opens in a new tab)

Upgrade RHEL:6 openssl-static to version 0:1.0.1e-16.el6_5.4 or higher.
This issue was patched in RHSA-2014:0015.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openssl-static package and not the openssl-static package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

The DTLS retransmission implementation in OpenSSL 1.0.0 before 1.0.0l and 1.0.1 before 1.0.1f 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 and cause a denial of service (application crash) by interfering with packet delivery, related to ssl/d1_both.c and ssl/t1_enc.c.
