In BIG-IP versions 15.1.0-15.1.0.4, 15.0.0-15.0.1.3, and 14.1.0-14.1.2.6, a BIG-IP virtual server with a Session Initiation Protocol (SIP) ALG profile, parsing SIP messages that contain a multi-part MIME payload with certain boundary strings can cause TMM to free memory to the wrong cache.

Potential Mitigations
- Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- For example, languages such as Java, Ruby, and Lisp perform automatic garbage collection that releases memory for objects that have been deallocated.
