Details
A vulnerability classified as critical has been found in F5 BIG-IP up to 14.1.5.2/15.1.8.0/16.1.3.2 (Firewall Software). This affects an unknown functionality of the component Traffic Management Microkernel. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on availability. The summary by CVE is:
On BIG-IP versions 16.1.x before 16.1.3.3, 15.1.x before 15.1.8.1, 14.1.x before 14.1.5.3, and all versions of 13.1.x, when a SIP profile is configured on a Message Routing type virtual server, undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
