AIX OpenSSL Advisory : openssl_advisory7.doc (Heartbleed)

High Nessus Plugin ID 73472

Synopsis

The remote AIX host is running a vulnerable version of OpenSSL.

Description

The version of OpenSSL running on the remote host is affected by an information disclosure vulnerability.

OpenSSL incorrectly handles memory in the TLS heartbeat extension, potentially allowing a remote attacker to read the contents of up to 64KB of server memory, potentially exposing passwords, private keys, and other sensitive data.

Solution

Install the appropriate interim fix. Additionally, to address this issue you must :

- Replace your SSL certificates by revoking existing certificates and reissuing new certificates, with a new private key generated by 'openssl genrsa'.

- Reset User Credentials Force users to reset their passwords and revoke any existing cookies or authentication prior to the re-authentication.
