CVE-2015-8098

Security Advisory

Original Publication Date: 01/06/2016 Updated Date: 01/06/2016

Vulnerability Description

An out-of-bounds memory vulnerability may allow an unauthenticated BIG-IP APM
user to cause a denial-of-service (DoS) or possibly perform remote code 
execution on a BIG-IP system processing a Citrix Remote Desktop connection 
through a virtual server that is configured with remote desktop profile. 
(CVE-2015-8098).

Impact

An unauthenticated remote attacker may be able to cause a denial-of-service 
(DoS) or perform remote code execution on an affected BIG-IP APM device.

Note: This vulnerability was identified internally, and there are no known 
exploits at this time.

Security Issue Status

F5 Product Development has assigned ID 489323 (BIG-IP) to this vulnerability,
and has evaluated the currently supported releases for potential 
vulnerability.

To determine if your release is known to be vulnerable, the components or 
features that are affected by the vulnerability, and for information about 
releases or hotfixes that address the vulnerability, refer to the following 
table:

Product		Versions known to be vulnerable	Versions known to be not vulnerable	Severity	Vulnerable component or feature

BIG-IP APM 	11.6.0 - 11.6.0 HF3 		12.0.0 					Severe 		Remote Desktop Profile 
		11.5.0 - 11.5.2 HF1 		11.6.0 HF4 - 11.6.0 HF6 
		11.4.1 - 11.4.1 HF8 		11.5.3 11.4.1 HF9 
						11.0.0 - 11.4.0
						10.1.0 - 10.2.4 
						11.4.1 HF9

Vulnerability Recommended Actions

If you are running a version listed in the Versions known to be vulnerable 
column, you can eliminate this vulnerability by upgrading to a version listed
in the Versions known to be not vulnerable column. If the table lists only an
older version than what you are currently running, or does not list a 
non-vulnerable version, then no upgrade candidate currently exists.

F5 responds to vulnerabilities in accordance with the Severity values 
published in the previous table. The Severity values and other security 
vulnerability parameters are defined in SOL4602: Overview of the F5 security 
vulnerability response policy.

To mitigate this vulnerability, you should permit access to the affected 
virtual servers only over a secure network, and restrict access to trusted 
users. Alternatively, you can remove the remote desktop profile from the 
virtual server if remote desktop functionality is not required.
