VOIP: SIP Negative Content Length
This signature detects attempts to exploit a known vulnerability against SIP client. A successful attack can result in a denial-of-service condition. .
Extended Description
NCH Software Office Intercom is prone to a remote denial-of-service vulnerability because it fails to properly handle specially crafted SIP 'INVITE' requests. Exploiting this issue allows remote attackers to cause a denial-of-service due to a NULL-pointer dereference. Due to the nature of this issue, remote code execution may be possible; this has not been confirmed. Office Intercom 5.20 is vulnerable; other versions may also be affected.
