Mac OS X Multiple Vulnerabilities (Security Update 2014-005) (POODLE) (Shellshock)

critical Nessus Plugin ID 78551

Synopsis

The remote host is missing a Mac OS X update that fixes multiple security issues.

Description

The remote host is running a version of Mac OS X 10.8 or 10.9 that does not have Security Update 2014-005 applied. This update contains several security-related fixes for the following issues :

- A command injection vulnerability in GNU Bash known as Shellshock. The vulnerability is due to the processing of trailing strings after function definitions in the values of environment variables. This allows a remote attacker to execute arbitrary code via environment variable manipulation depending on the configuration of the system. (CVE-2014-6271, CVE-2014-7169)

- A man-in-the-middle (MitM) information disclosure vulnerability known as POODLE. The vulnerability is due to the way SSL 3.0 handles padding bytes when decrypting messages encrypted using block ciphers in cipher block chaining (CBC) mode. A MitM attacker can decrypt a selected byte of a cipher text in as few as 256 tries if they are able to force a victim application to repeatedly send the same data over newly created SSL 3.0 connections. (CVE-2014-3566)

Note that successful exploitation of the most serious issues can result in arbitrary code execution.

Solution

Install Security Update 2014-005 or later.
