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).
Affected configurations
• linux linux kernel (<= 2.6.31)
• linux linux kernel 2.6.31
• debian debian linux 4.0
• debian debian linux 5.0
• canonical ubuntu linux 6.06
• canonical ubuntu linux 8.04
