An issue was discovered in the America's Army Proving Grounds platform for the Unreal Engine. With a false packet sent via UDP, the application server responds with several bytes, giving the possibility of DoS amplification, even being able to be used in DDoS attacks.

America's Army (aka AA or Army Game Project) 2.8.3.1 and earlier allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a crafted UDP packet, probably involving a VoiceIndex value that is outside of the range specified by VOICE_MAX_CHATTERS.

Multiple buffer overflows in the logging function in the Unreal engine, as used by America's Army and America's Army Special Forces 2.8.2 and earlier, when Punkbuster (PB) is enabled, allow remote attackers to cause a denial of service (daemon crash) via a long (1) PB_Y packet to the YPG server on UDP port 1716 or (2) PB_U packet to UCON on UDP port 1716, different vectors than CVE-2007-4442. NOTE: this issue might be in Punkbuster itself, but there are insufficient details to be certain.

The Windows dedicated server for the Unreal engine, as used by America's Army and America's Army Special Forces 2.8.2 and earlier, when Punkbuster (PB) is enabled, allows remote attackers to cause a denial of service (server hang) via packets containing 0x07 characters or other unspecified invalid characters. NOTE: this issue may overlap CVE-2007-4443. NOTE: this issue might be in Punkbuster itself, but there are insufficient details to be certain.
