CVE-2009-1895 (GCVE-0-2009-1895)

Vulnerability from cvelistv5 – Published: 2009-07-16 15:00 – Updated: 2024-08-07 05:27
VLAI?
Summary
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).
Severity ?
No CVSS data available.
CWE
