CVE-2014-8176

Status Candidate

Overview

The dtls1_clear_queues function in ssl/d1_lib.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h 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.

Red Hat Security Advisory 2015-1115-01
Posted Jun 15, 2015
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2015-1115-01 - OpenSSL is a toolkit that implements the Secure Sockets Layer and Transport Layer Security protocols, as well as a full-strength, general purpose cryptography library. An invalid free flaw was found in the way OpenSSL handled certain DTLS handshake messages. A malicious DTLS client or server could cause a DTLS server or client using OpenSSL to crash or, potentially, execute arbitrary code. A flaw was found in the way the OpenSSL packages shipped with Red Hat Enterprise Linux 6 and 7 performed locking in the ssleay_rand_bytes() function. This issue could possibly cause a multi-threaded application using OpenSSL to perform an out-of-bounds read and crash.

Ubuntu Security Notice USN-2639-1
Posted Jun 11, 2015
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 2639-1 - Praveen Kariyanahalli, Ivan Fratric and Felix Groebert discovered that OpenSSL incorrectly handled memory when buffering DTLS data. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service, or possibly execute arbitrary code. Joseph Barr-Pixton discovered that OpenSSL incorrectly handled malformed ECParameters structures. A remote attacker could use this issue to cause OpenSSL to hang, resulting in a denial of service. Various other issues were also addressed.
