5.0
CVSS v3.1
Official Description
Integer underflow in Armed Assault (aka ArmA) 1.14 and earlier, and 1.16 beta, and Armed Assault II 1.02 and earlier allows remote attackers to cause a denial of service (crash) via a VoIP over Network (VON) packet to port 2305 with a negative packet_size value, which triggers a buffer over-read.
Technical Analysis
CVE-2009-2547 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.
