VOIP: Digium Asterisk UDPTL Processing Heap Buffer Overflow
This signature detects attempts to exploit a known vulnerability against Digium Asterisk. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of the affected server.
Extended Description
Asterisk is prone to multiple remote buffer-overflow vulnerabilities because the application fails to perform adequate boundary checks on user-supplied data. An attacker can exploit these issues to execute arbitrary code within the context of the affected application or to crash the application, denying service to legitimate users.
