CVE-2008-0923 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-0923): Directory traversal vulnerability in the Shared Folders feature for VMWare ACE 1.0.2 and 2.0.2, Player 1.0.4 and 2.0.2, and Workstation 5.5.4 and 6.0.2 allows guest OS users to read and write arbitrary files on the host OS via a multibyte string that produces a wide character string containing .. (dot dot) sequences, which bypasses the protection mechanism, as demonstrated using a "%c0%2e%c0%2e" string.
Upstream failed to provide an update to their products since November, now this is public. We can either mask, wait, or send an advisory with the "disable shared folder" workaround.
Good news: Vmware upstream states that only windows-hosted machines are affected, i.e. not an issue for us. Thanks to nion for pointing that out for me. http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1004034
