On BIG-IP 13.1.0-13.1.0.7, a remote attacker using undisclosed methods against virtual servers configured with a Client SSL or Server SSL profile that has the SSL Forward Proxy feature enabled can force the Traffic Management Microkernel (tmm) to leak memory. As a result, system memory usage increases over time, which may eventually cause a decrease in performance or a system reboot due to memory exhaustion. En BIG-IP 13.1.0-13.1.0.7, un atacante remoto que emplea métodos no revelados contra servidores virtuales configurados con un perfil Client SSL o Server SSL con la característica SSL Forward Proxy habilitada puede forzar al TMM (Traffic Management Microkernel) a filtrar memoria. Como resultado, el uso de la memoria del sistema aumenta con el tiempo, lo que podría provocar un descenso del rendimiento o un reinicio del sistema debido al agotamiento de memoria. • http://www.securitytracker.com/id/1041196 https://support.f5.com/csp/article/K20134942 • CWE-772: Missing Release of Resource after Effective Lifetime •

On F5 BIG-IP 13.1.0-13.1.0.3, 13.0.0, 12.1.0-12.1.3.3, 11.6.1-11.6.3.1, 11.5.1-11.5.5, or 11.2.1, a malformed TLS handshake causes TMM to crash leading to a disruption of service. This issue is only exposed on the data plane when Proxy SSL configuration is enabled. The control plane is not impacted by this issue. En F5 BIG-IP, 13.1.0-13.1.0.3, 13.0.0, 12.1.0-12.1.3.3, 11.6.1-11.6.3.1, 11.5.1-11.5.5 o en la versión 11.2.1, un handshake TLS mal formado hace que TMM se cierre inesperadamente, lo que conduce a una interrupción del servicio. Este problema solo se expone en el plano de datos cuando la configuración Proxy SSL está habilitada. • http://www.securitytracker.com/id/1041017 https://support.f5.com/csp/article/K46940010 • CWE-20: Improper Input Validation •

On F5 BIG-IP 13.0.0-13.1.0.5 or 12.0.0-12.1.3.3, malicious root users with access to a VCMP guest can cause a disruption of service on adjacent VCMP guests running on the same host. Exploiting this vulnerability causes the vCMPd process on the adjacent VCMP guest to restart and produce a core file. This issue is only exploitable on a VCMP guest which is operating in "host-only" or "bridged" mode. VCMP guests which are "isolated" are not impacted by this issue and do not provide mechanism to exploit the vulnerability. Guests which are deployed in "Appliance Mode" may be impacted however the exploit is not possible from an Appliance Mode guest. • http://www.securitytracker.com/id/1040797 https://support.f5.com/csp/article/K03165684 •

On F5 BIG-IP 13.0.0-13.1.0.5, 12.1.0-12.1.2, or 11.2.1-11.6.3.1, Enterprise Manager 3.1.1, BIG-IQ Centralized Management 5.0.0-5.4.0 or 4.6.0, BIG-IQ Cloud and Orchestration 1.0.0, or F5 iWorkflow 2.0.2-2.3.0, authenticated users granted TMOS Shell (tmsh) access can access objects on the file system which would normally be disallowed by tmsh restrictions. This allows for authenticated, low privileged attackers to exfiltrate objects on the file system which should not be allowed. En F5 BIG-IP 13.0.0-13.1.0.5, 12.1.0-12.1.2 o 11.2.1-11.6.3.1, Enterprise Manager 3.1.1, BIG-IQ Centralized Management 5.0.0-5.4.0 o 4.6.0, BIG-IQ Cloud and Orchestration 1.0.0 o F5 iWorkflow 2.0.2-2.3.0, los usuarios autenticados que tengan acceso TMOS Shell (tmsh) pueden acceder a objetos en el sistema de archivos a los que normalmente no tendrían acceso por las restricciones de tmsh. Esto permite que atacantes autenticados con bajos privilegios exfiltren objetos en el sistema de archivos, algo que no deberían poder hacer. • http://www.securitytracker.com/id/1040799 http://www.securitytracker.com/id/1040800 https://support.f5.com/csp/article/K37442533 • CWE-732: Incorrect Permission Assignment for Critical Resource •
