The cap_bprm_set_creds function in security/commoncap.c in the Linux kernel
before 3.3.3 does not properly handle the use of file system capabilities
(aka fcaps) for implementing a privileged executable file, which allows
local users to bypass intended personality restrictions via a crafted
application, as demonstrated by an attack that uses a parent process to
disable ASLR.
