sol15401: OpenSSL vulnerability CVE-2012-2333 Security Advisory

Original Publication Date: 07/09/2014

Description

Integer underflow in OpenSSL before 0.9.8x, 1.0.0 before 1.0.0j, and 1.0.1 
before 1.0.1c, when TLS 1.1, TLS 1.2, or DTLS is used with CBC encryption, 
allows remote attackers to cause a denial of service (buffer over-read) or 
possibly have unspecified other impact via a crafted TLS packet that is not 
properly handled during a certain explicit IV calculation. (CVE-2012-2333)

Impact

Remote attackers may be able to cause a denial-of-service (DoS).

Status

F5 Product Development has assigned ID 376840 (BIG-IP and Enterprise Manager)
and ID 410742 (ARX) to this vulnerability, and has evaluated the currently 
supported releases for potential vulnerability.

Recommended action

You can eliminate this vulnerability by running a version listed in the 
Versions known to be not vulnerable column in the previous table. If the 
Versions known to be not vulnerable column does not list a version that is 
higher than the version you are running, then no upgrade candidate currently 
exists.

Mitigating this vulnerability

To mitigate this vulnerability, you should consider the following 
recommendations:

    Consider denying access to the Configuration utility and using only the 
command line and tmsh utility until the BIG-IP system is updated. If that is 
not possible, F5 recommends that you access the Configuration utility over 
only a secure network. If SSL profiles are configured to use COMPAT ciphers, 
consider reconfiguring the profiles to use ciphers from the NATIVE SSL stack.
For information about the NATIVE and COMPAT ciphers, refer to the following 
articles:

        SOL13163: SSL ciphers supported on BIG-IP platforms (11.x)

        SOL13171: Configuring the cipher strength for SSL profiles (11.x)

        SOL13187: COMPAT SSL ciphers are no longer included in standard cipher
strings

ARX

If the previous table lists a version in the Versions known to be not 
vulnerable column, you can eliminate this vulnerability by upgrading to the 
listed version. If the table does not list any version in the column, then no
upgrade candidate currently exists.

To mitigate this vulnerability, you should permit access to the ARX GUI only 
over a secure network.
