Original NVD Description

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.
