CVE-2009-1895 at MITRE

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).

Note from the SUSE Security Team

This CVE specifies a bug that could disable the 'mmap_min_addr' protection in the kernel. This protection was added in the 2.6.25 mainline kernel, so by default exists in openSUSE 11.0, 11.1 and SUSE Linux Enterprise 11 and newer products. We backported the 'mmap_min_addr' protection also to SUSE Linux Enterprise 10 SP3, but not to older products. So older products did not need to get fixes for this.

This issue does not reference an actual security issue. You need a second bug to actually exploit this problem.
