On BIG-IP 15.0.0-15.0.1.2, 14.1.0-14.1.2.2, 13.1.0-13.1.3.2, 12.1.0-12.1.5, and 11.5.2-11.6.5.1 and BIG-IQ 7.0.0, 6.0.0-6.1.0, and 5.2.0-5.4.0, users with non-administrator roles (for example, Guest or Resource Administrator) with tmsh shell access can execute arbitrary commands with elevated privilege via a crafted tmsh command.
An excessive resource consumption flaw was found in the way the Linux kernel's networking subsystem processed TCP segments. If the Maximum Segment Size (MSS) of a TCP connection was set to low values, such as 48 bytes, it can leave as little as 8 bytes for the user data, which significantly increases the Linux kernel's resource (CPU, Memory, and Bandwidth) utilization. A remote attacker could use this flaw to cause a denial of service (DoS) by repeatedly sending network traffic on a TCP connection with low TCP MSS.
On BIG-IP 15.0.0-15.0.1, 14.1.0-14.1.2, 14.0.0-14.0.1, and 13.1.0-13.1.3.1, under certain conditions tmm may leak memory when processing packet fragments, leading to resource starvation.
On BIG-IP 15.0.0-15.0.1, 14.1.0-14.1.2, 14.0.0-14.0.1, 13.1.0-13.1.3.1, 12.1.0-12.1.5, and 11.5.1-11.6.5.1, undisclosed traffic flow may cause TMM to restart under some circumstances.
