Linux Distros Unpatched Vulnerability : CVE-2015-2808

critical Nessus Plugin ID 218959

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 RC4 algorithm, as used in the TLS protocol and SSL protocol, does not properly combine state data with key data during the initialization phase, which makes it easier for remote attackers to conduct plaintext- recovery attacks against the initial bytes of a stream by sniffing network traffic that occasionally relies on keys affected by the Invariance Weakness, and then using a brute-force approach involving LSB values, aka the Bar Mitzvah issue. (CVE-2015-2808)

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

Solution

There is no known solution at this time.
