SIP: Header Value URI Type Overflow
This signature detects a maliciously crafted Session Initiation Protocol (SIP) request containing a malformed SIP URI. The improperly formatted URI can be designed to exploit a buffer overflow condition in a device that handles the SIP protocol.
Extended Description
Successful exploitation would allow for arbitrary code injection and execution with the privileges of the user running the SIP application. Code injection that does not result in execution would crash the application due to memory corruption and would result in the denial of service condition.
