5238686bc453229b4aceceb879e2d11abd43881bf84eafdc99cb6eaafadf1cacMicrosoft Distributed Transaction Coordinator DoS - A flaw in the way MSDTC handles malformed packets could allow an attacker to hang the service and exhaust resources on the Server. If an attacker sends 20200 null characters to the MSDTC service, which listens on TCP port 3372, server resources are allocated poorly. This attack can result in MSDTC.EXE spiking at 100% cpu usage, MSDTC refusing connections and kernel resources being exhausted. This was fixed with MS02-018, although the security bulletin does not mention this vulnerability.

d27278de1182e49dc003e21db2c36a8adea55112733bdca6d516e9cfd57786bfA flaw in internal object interaction allows malicious users to bring down Internet Information Server 4.0, 5.0 and 5.1 with FP2002. Frontpage contains URL parsers for dynamic components (shtml.exe/dll). If a malicious user issues a request for /_vti_bin/shtml.exe where the URL for the dynamic contents is replaced with a long URL, the submodule will filter out the URL, and return a null value to the web service URL parser, crashing IIS. Microsoft advisory on this vulnerability here.
