Overview

CVE-2010-3858 is a medium-severity vulnerability affecting linux linux_kernel. It was published on November 30, 2010 and has a CVSS 2.0 base score of 4.9 (MEDIUM).

This vulnerability has a CVSS 2.0 base score of 4.9, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
