RHEL 5 : nss (Unpatched Vulnerability)

high Nessus Plugin ID 199394

Synopsis

The remote Red Hat 5 host is affected by multiple vulnerabilities that will not be patched.

Description

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

 - Mozilla NSS: Errors in mp_div and mp_exptmod cryptographic functions (CVE-2016-1938)

 - SSL/TLS: Birthday attack against 64-bit block ciphers (SWEET32) (CVE-2016-2183)

 - 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-2011-3389)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

Solution

The vendor has acknowledged the vulnerabilities but no solution has been provided. Refer to the vendor for remediation guidance.
