Overview

CVE-2010-0003 is a medium-severity vulnerability affecting linux linux_kernel. It was published on January 26, 2010 and has a CVSS 2.0 base score of 5.4 (MEDIUM).

This vulnerability has a CVSS 2.0 base score of 5.4, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

The print_fatal_signal function in kernel/signal.c in the Linux kernel before 2.6.32.4 on the i386 platform, when print-fatal-signals is enabled, allows local users to discover the contents of arbitrary memory locations by jumping to an address and then reading a log file, and might allow local users to cause a denial of service (system slowdown or crash) by jumping to an address.

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.
