SOL15147: OpenSSL vulnerability CVE-2013-6449

Security AdvisorySecurity Advisory

Original Publication Date: 04/10/2014


The ssl_get_algorithm2 function in ssl/s3_lib.c in OpenSSL before 1.0.2 
obtains a certain version number from an incorrect data structure, which 
allows remote attackers to cause a denial of service (daemon crash) via 
crafted traffic from a TLS 1.2 client. (CVE-2013-6449)


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


F5 Product Development has assigned ID 442452 (BIG-IP) and ID 410742 (ARX) to 
this vulnerability.

Recommended action

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

To mitigate this vulnerability, you should consider the following 
- - Limit the Configuration utility access to a trusted management network.
- - Ensure that the SSL profiles are configured to use SSL ciphers from the 
NATIVE SSL stack. Starting in BIG-IP 10.2.3 and 11.0.0, commonly used cipher 
strings (excluding the COMPAT string) only include ciphers from the NATIVE SSL 
stack, and do not include SSL ciphers from the COMPAT SSL stack. For example, 
the following cipher strings only include ciphers from the NATIVE SSL stack:
	- ALL
	- LOW
	- EXP
