CVE-2014-8176  (opens in a new tab)
CWE-119  (opens in a new tab)

Upgrade openssl to version 1.0.1h, 1.0.0m, 0.9.8za or higher.

Overview

Affected versions of this package are vulnerable to Out-of-Bounds. The dtls1_clear_queues function in ssl/d1_lib.c frees data structures without considering that application data can arrive between a ChangeCipherSpec message and a Finished message, which allows remote DTLS peers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via unexpected application data.
