Official Description
Buffer overflow in the Session Initiation Protocol (SIP) User Access Client (UAC) message parsing module in Avaya one-X Desktop Edition 2.1.0.70 and earlier allows remote attackers to cause a denial of service (call reception outage) via a malformed SIP message.

CVE-2007-3318 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
