CVE-2014-0198  (opens in a new tab)
CWE-476  (opens in a new tab)

How to fix?

Upgrade Centos:6 openssl to version 0:1.0.1e-16.el6_5.14 or higher.

NVD Description

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

The do_ssl3_write function in s3_pkt.c in OpenSSL 1.x through 1.0.1g, when SSL_MODE_RELEASE_BUFFERS is enabled, does not properly manage a buffer pointer during certain recursive calls, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via vectors that trigger an alert condition.
