Technical details
A stack exhaustion vulnerability exists in the DecodeHeaderComponent function of SipStack.cpp, caused by unbounded mutual recursion in header parsing. The flaw allows remote attackers to send specially crafted SIP packets that trigger recursive calls without proper depth limits, exhausting the stack and crashing the process. No authentication or user interaction is required for exploitation.
