CVE-2010-3858

What it is

The setup_arg_pages function in fs/exec.c in the Linux kernel before 2.6.36, when CONFIG_STACK_GROWSDOWN is used, does not properly restrict the stack memory consumption of the (1) arguments and (2) environment for a 32-bit application on a 64-bit platform, which allows local users to cause a denial of service (system crash) via a crafted exec system call, a related issue to CVE-2010-2240.
