Bugzilla: 606611: CVE-2010-2240 kernel: mm: keep a guard page below a grow-down stack segment
IAVA: 2011-A-0066


The MITRE CVE dictionary describes this issue as:

The do_anonymous_page function in mm/memory.c in the Linux kernel before, 2.6.32.x before, 2.6.34.x before, and 2.6.35.x before does not properly separate the stack and the heap, which allows context-dependent attackers to execute arbitrary code by writing to the bottom page of a shared memory segment, as demonstrated by a memory-exhaustion attack against the X.Org X server.
