• CVSS Severity Rating • Fix Information • Vulnerable Software Versions • SCAP Mappings • CPE Information

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).
