The Perforce service (p4s.exe) in Perforce Server 2007.3/143793 and earlier allows remote attackers to cause a denial of service (daemon crash) via a missing parameter to the (1) dm-FaultFile, (2) dm-LazyCheck, (3) dm-ResolvedFile, (4) dm-OpenFile, (5) crypto, and possibly unspecified other commands, which triggers a NULL pointer dereference.

The Perforce service (p4s.exe) in Perforce Server 2007.3/143793 and earlier allows remote attackers to cause a denial of service (daemon crash) via a (1) server-DiffFile or (2) server-ReleaseFile command with a large integer value, which is used in an array initialization calculation, and leads to invalid memory access.

The Perforce client does not restrict the set of files that it overwrites upon receiving a request from the server, which allows remote attackers to overwrite arbitrary files by modifying the client config file on the server, or by operating a malicious server.
