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.

• linux linux kernel (>= 3.1 < 3.2.16)
• linux linux kernel (>= 3.3 < 3.3.3)
