|Bugzilla:||645222: CVE-2010-3858 kernel: setup_arg_pages: diagnose excessive argument size|
The MITRE CVE dictionary describes this issue as:
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.
This issue did not affect the versions of Linux kernel as shipped with Red Hat
Enterprise Linux 4 as they did not backport the upstream commit b6a2fea3 that introduced the issue. This was addressed in Red Hat Enterprise Linux 5 and Red Hat Enterprise MRG via https://rhn.redhat.com/errata/RHSA-2011-0004.html and
https://rhn.redhat.com/errata/RHSA-2010-0958.html. Future kernel updates in Red Hat Enterprise Linux 6 may address this flaw.
