AIX OpenSSL Advisory : openssl_advisory11.asc (POODLE)

high Nessus Plugin ID 78772

Language:

Synopsis

The remote AIX host has a version of OpenSSL installed that is affected by multiple vulnerabilities.

Description

The version of OpenSSL installed on the remote host is affected by the following vulnerabilities :

- An error exists related to DTLS SRTP extension handling and specially crafted handshake messages that can allow denial of service attacks via memory leaks.
(CVE-2014-3513)

- 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. MitM attackers 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)

- An error exists related to session ticket handling that can allow denial of service attacks via memory leaks.
(CVE-2014-3567)

Solution

A fix is available and can be downloaded from the AIX website.

IMPORTANT : If possible, it is recommended that a mksysb backup of the system be created. Verify that it is both bootable and readable before proceeding.
