Linux Distros Unpatched Vulnerability : CVE-2012-4929

high Nessus Plugin ID 217776

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - The TLS protocol 1.2 and earlier, as used in Mozilla Firefox, Google Chrome, Qt, and other products, can encrypt compressed data without properly obfuscating the length of the unencrypted data, which allows man- in-the-middle attackers to obtain plaintext HTTP headers by observing length differences during a series of guesses in which a string in an HTTP request potentially matches an unknown string in an HTTP header, aka a CRIME attack. (CVE-2012-4929)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
