CVE ID:	CVE-2009-1895
Description:	The personality subsystem in the Linux kernel before 2.6.31-rc3 has a PER_CLEAR_ON_SETID setting that does not clear the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags when executing a setuid or setgid program, which makes it easier for local users to leverage the details of memory usage to (1) conduct NULL pointer dereference attacks, (2) bypass the mmap_min_addr protection mechanism, or (3) defeat address space layout randomization (ASLR).
Test IDs:	1.3.6.1.4.1.25623.1.0.64553   1.3.6.1.4.1.25623.1.0.64551   1.3.6.1.4.1.25623.1.0.64556   1.3.6.1.4.1.25623.1.0.64555
