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.

The UCC dedicated server for the Unreal engine, possibly 2003 and 2004, on Windows allows remote attackers to cause a denial of service (continuous beep and server slowdown) via a string containing many 0x07 characters in (1) a request to the images/ directory, (2) the Content-Type field, (3) a HEAD request, and possibly other unspecified vectors.
