CVE-2002-2295

Exp

Buffer overflow in Pico Server (pServ) 2.0 beta 1 through beta 5 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via (1) a 1024-byte TCP stream message, which triggers an off-by-one buffer overflow, or (2) a long method name in an HTTP request, (3) a long version number in an HTTP request, (4) a long User-Agent header, or (5) a long file path.
