===================================================================== CERT-Renater Note d'Information No. 2014/VULN102 _____________________________________________________________________ DATE : 10/04/2014 HARDWARE PLATFORM(S): F5 products. OPERATING SYSTEM(S): F5 Products software. ====================================================================== http://support.f5.com/kb/en-us/solutions/public/15000/100/sol15159.html ______________________________________________________________________ SOL15159: OpenSSL vulnerability CVE-2014-0160 Security AdvisorySecurity Advisory Original Publication Date: 04/08/2014 Description The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeat Extension packets, which allows remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read, as demonstrated by reading private keys, related to d1_both.c and t1_lib.c, aka the Heartbleed bug.(CVE-2014-0160) Impact Systems that are vulnerable can be exploited to retrieve information from memory. That information may include the private keys used for TLS/DTLS. - - Virtual servers using an SSL profile configured with the default Native SSL ciphers are not vulnerable. Only virtual servers using an SSL profile configured to use ciphers from the Compat SSL stack are vulnerable. In addition, back-end resources are not protected by virtual servers that do not use SSL profiles and pass SSL traffic directly through to the back-end web servers. - - The Configuration utility on the management interface is vulnerable. - - Clients using the BIG-IP Edge client for Android are not vulnerable to this vulnerability. However, clients using the BIG-IP Edge client for Windows, Mac OS, or Linux are vulnerable if they are used to connect to a compromised FirePass or BIG-IP APM system. Status F5 Product Development has assigned ID 456033 (BIG-IP) to this 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 Versions known to Vulnerable be vulnerable be not vulnerable component or feature BIG-IP LTM 11.5.0 - 11.5.1 11.0.0 - 11.4.1 Configuration utility 10.0.0 - 10.2.4 Compat SSL ciphers BIG-IP AAM 11.5.0 - 11.5.1 11.4.0 - 11.4.1 Configuration utility Compat SSL ciphers BIG-IP AFM 11.5.0 - 11.5.1 11.3.0 - 11.4.1 Configuration utility None Compat SSL ciphers BIG-IP 11.5.0 - 11.5.1 11.0.0 - 11.4.1 Configuration utility Analytics None Compat SSL ciphers BIG-IP APM 11.5.0 - 11.5.1 11.0.0 - 11.4.1 Configuration utility 10.1.0 - 10.2.4 Compat SSL ciphers None BIG-IP ASM 11.5.0 - 11.5.1 11.0.0 - 11.4.1 Configuration utility 10.0.0 - 10.2.4 Compat SSL ciphers None BIG-IP Edge None 11.0.0 - 11.3.0 None Gateway 10.1.0 - 10.2.4 BIG-IP GTM 11.5.0 - 11.5.1 11.0.0 - 11.4.1 Configuration utility 10.0.0 - 10.2.4 Compat SSL ciphers None BIG-IP Link 11.5.0 - 11.5.1 11.0.0 - 11.4.1 Configuration utility Controller 10.0.0 - 10.2.4 Compat SSL ciphers BIG-IP PEM 11.5.0 - 11.5.1 11.3.0 - 11.4.1 Configuration utility Compat SSL ciphers BIG-IP PSM 11.5.0 - 11.5.1 11.0.0 - 11.4.1 Configuration utility 10.0.0 - 10.2.4 Compat SSL ciphers None BIG-IP None 11.0.0 - 11.3.0 None WebAccelerator 10.0.0 - 10.2.4 BIG-IP WOM None 11.0.0 - 11.3.0 None 10.0.0 - 10.2.4 ARX None 6.0.0 - 6.4.0 None Enterprise None 3.0.0 - 3.1.1 None Manager 2.1.0 - 2.3.0 FirePass None 7.0.0 None 6.0.0 - 6.1.0 BIG-IQ Cloud None 4.0.0 - 4.3.0 None BIG-IQ Device None 4.2.0 - 4.3.0 None BIG-IQ Security None 4.0.0 - 4.3.0 None BIG-IP Edge None 2.0.3 - 2.0.4 None Clients for Android BIG-IP Edge 2.0.0 - 2.0.1 1.0.0 - 1.0.4 VPN Clients for 1.0.6 Apple iOS BIG-IP Edge 7080 - 7101 6035 - 7071 VPN Clients for Linux BIG-IP Edge 7080 - 7101 6035 - 7071 VPN Clients for MAC OS X BIG-IP Edge 7080 - 7101 6035 - 7071 VPN Clients for Windows Recommended action 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 consider the following recommendations: - - Limit the Configuration utility access to a trusted management network. - - Use only Native SSL stack ciphers. Do not use ciphers from the Compat SSL stack. For information about the Native and Compat ciphers, refer to SOL13163: SSL ciphers supported on BIG-IP platforms (11.x). - - Back-end resources are not protected by virtual servers that do not use SSL profiles and pass SSL traffic through to the back-end web servers. When possible, you should protect back-end resources by using SSL profiles to terminate SSL at the BIG-IP.
