Description

VMWare Workstation (up to and including 9.0.2 build-1031769)
and Player have a setuid executable called vmware-mount that
invokes lsb_release in the PATH with popen(3). Since PATH is
user-controlled, and the default system shell on
Debian-derived distributions does not drop privs, we can put
an arbitrary payload in an executable called lsb_release and
have vmware-mount happily execute it as root for us.
