The cvs client blindly trust paths returned to it by the server. Therefore, a cvs client could be tricked into creating a file anywhere on the system by a malicious server.
This problem can be tested yourself as follows. Although this example
runs a faked cvs server using the :ext: method, this vulnerability is
available with any method (including :pserver: of course).

There is a buffer overflow in the HELO command of the smtp gateway which ships as part of the VirusWall product. This buffer overflow could be used to launch arbitrary code on the vulnerable server.
This issue was patched by InterScan, however even with the patch it is possible to cause a DoS of the mail server software by sending between 4075 and 4090 characters.
