CVE-2010-3858: Canonical Ubuntu Linux

Medium severity, CVSS 4.9. EPSS: 0.9% chance of exploitation in the next 30 days.

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.

Affected products

• Canonical Ubuntu Linux: version 9.10 only; version 10.04 only; version 10.10 only
• Debian Debian Linux: version 5.0 only
• Linux Linux Kernel: before 2.6.36 (fixed in 2.6.36)
