http://secunia.com/advisories/16008/

CRITICAL:
Moderately critical

IMPACT:
Security Bypass

WHERE:
>From remote

OPERATING SYSTEM:
BIG-IP 9.x
http://secunia.com/product/3158/

DESCRIPTION:
A vulnerability has been reported in BIG-IP, which potentially can be
exploited by malicious people to bypass certain security
restrictions.

The vulnerability is caused due to an unspecified error in the SSL
authentication and can be exploited to subvert SSL connections
terminating on a vulnerable device.

The vulnerability affects versions 9.0.2 through 9.1.

SOLUTION:
The vendor has issued a security update for versions 9.0.4, 9.0.5,
and 9.1.
ftp://ftp.f5.com/Domestic/bigip/bigip9x-hotfix-CR49528/

As a workaround, the vendor recommends temporarily disabling NATIVE
ciphers on any clientssl or serverssl profiles that require or
request authentication. This may result in a loss of SSL performance.

PROVIDED AND/OR DISCOVERED BY:
