Detailsinfo

A vulnerability classified as problematic was found in Apple Mac OS X up to 10.8 (Operating System). This vulnerability affects an unknown functionality of the component CFNetwork SSL. The manipulation with an unknown input leads to a input validation vulnerability. The CWE definition for the vulnerability is CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. As an impact it is known to affect confidentiality, and integrity. CVE summarizes:

The SSL protocol, as used in certain configurations in Microsoft Windows and Microsoft Internet Explorer, Mozilla Firefox, Google Chrome, Opera, and other products, encrypts data by using CBC mode with chained initialization vectors, which allows man-in-the-middle attackers to obtain plaintext HTTP headers via a blockwise chosen-boundary attack (BCBA) on an HTTPS session, in conjunction with JavaScript code that uses (1) the HTML5 WebSocket API, (2) the Java URLConnection API, or (3) the Silverlight WebClient API, aka a "BEAST" attack.

The weakness was published 10/22/2013 by Juliano Rizzo as APPLE-SA-2013-10-22-3 as confirmed mailinglist post (Apple Security Mailinglist). The advisory is shared for download at lists.apple.com. The mailinglist post contains:

Only the SSLv3 and TLS 1.0 versions of SSL were used. These versions are subject to a protocol weakness when using block ciphers. A man-in-the-middle attacker could have injected invalid data, causing the connection to close but revealing some information about the previous data. If the same connection was attempted repeatedly the attacker may eventually have been able to decrypt the data being sent, such as a password. This issue was addressed by enabling TLS 1.2.
This vulnerability was named CVE-2011-3389 since 09/05/2011. The exploitation appears to be difficult. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. There are neither technical details nor an exploit publicly available.

It is assigned to the family Oracle Linux Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 91499 (Microsoft Azure Stack 1809 Multiple Security Vulnerabilities).

Upgrading to version 10.9 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (68373), SecurityFocus (BID 49778†), OSVDB (74829†), Secunia (SA45791†) and SecurityTracker (ID 1025997†).
