Vulnerability Summary for CVE-2003-0985

Original release date: 01/20/2004
Last revised: 09/05/2008
Source: US-CERT/NIST

Overview

The mremap system call (do_mremap) in Linux kernel 2.4.x before 2.4.21, and possibly other versions before 2.4.24, does not properly perform bounds checks, which allows local users to cause a denial of service and possibly gain privileges by causing a remapping of a virtual memory area (VMA) to create a zero length VMA, a different vulnerability than CAN-2004-0077.

Impact

CVSS Severity (version 2.0):
CVSS v2 Base Score: 7.2 (HIGH) (AV:L/AC:L/Au:N/C:C/I:C/A:C) (legend)
Impact Subscore: 10.0
Exploitability Subscore: 3.9
CVSS Version 2 Metrics:
Access Vector: Locally exploitable
Access Complexity: Low
Authentication: Not required to exploit
Impact Type: Allows unauthorized disclosure of information; Allows unauthorized modification; Allows disruption of service
