Problem

Multiple vulnerabilities have been resolved in the Juniper Networks Session and Resource Control (SRC) software. The following is a summary of these vulnerabilities and their status:

CVE	CVSS	Summary
CVE-2011-3389	4.3 (AV:N/AC:M/Au:N/C:P/I:N/A:N)	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.
CVE-2016-2183	7.5 ( CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N )	The DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec protocols and other protocols and products, have a birthday bound of approximately four billion blocks, which makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long-duration encrypted session, as demonstrated by an HTTPS session using Triple DES in CBC mode, aka a "Sweet32" attack.

Solution

These issues have been resolved in SRC 4.12.0-R1 and all subsequent releases.
