The VFS subsystem in the Linux kernel 3.x provides an incomplete set of
requirements for setattr operations that underspecifies removing extended
privilege attributes, which allows local users to cause a denial of service
(capability stripping) via a failed invocation of a system call, as
demonstrated by using chown to remove a capability from the ping or
Wireshark dumpcap program.
