Synopsis:	Important: kernel security update
Issue date:	2010-08-30
CVE Names:	CVE-2010-2240

This update fixes the following security issue:

* when an application has a stack overflow, the stack could silently
overwrite another memory mapped area instead of a segmentation fault
occurring, which could cause an application to execute arbitrary code,
possibly leading to privilege escalation. It is known that the X Window
System server can be used to trigger this flaw. (CVE-2010-2240, Important)

The system must be rebooted for this update to take effect.
