Detailsinfo

A vulnerability, which was classified as critical, was found in Apple Mac OS X up to 10.9.4 (Operating System). Affected is the function dtls1_reassemble_fragment of the file d1_both.c of the component Messages. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The dtls1_reassemble_fragment function in d1_both.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly validate fragment lengths in DTLS ClientHello messages, which allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow and application crash) via a long non-initial fragment.

The weakness was released 09/17/2014 as HT6443 as confirmed advisory (Website). The advisory is shared for download at support.apple.com. This vulnerability is traded as CVE-2014-0195 since 12/03/2013. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication.
