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.
Note:References are provided for the convenience of the reader to help distinguish between vulnerabilities. The list is not intended to be complete.
