Vulnerability Summary for CVE-2006-2444

Original release date: 05/25/2006
Last revised: 03/07/2011
Source: US-CERT/NIST

Overview

The snmp_trap_decode function in the SNMP NAT helper for Linux kernel before 2.6.16.18 allows remote attackers to cause a denial of service (crash) via unspecified remote attack vectors that cause failures in snmp_trap_decode that trigger (1) frees of random memory or (2) frees of previously-freed memory (double-free) by snmp_trap_decode as well as its calling function, as demonstrated via certain test cases of the PROTOS SNMP test suite.

Impact

CVSS Severity (version 2.0):
CVSS v2 Base Score: 7.8 (HIGH) (AV:N/AC:L/Au:N/C:N/I:N/A:C) (legend)
Impact Subscore: 6.9
Exploitability Subscore: 10.0
CVSS Version 2 Metrics:
Access Vector: Network exploitable
Access Complexity: Low
Authentication: Not required to exploit
Impact Type: Allows disruption of service

Solution

Successful exploitation requires that the "ip_nat_snmp_basic" module is loaded and that traffic NAT is enabled on port 161 or 162. This vulnerability is addressed in the following product release: Linux, Linux Kernel, 2.6.16.18
