CVE-2006-2444

High
Published: Translated: NVD NIST

Summary

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

Risk Assessment

The risk is the potential for remote attackers to crash the system, causing service disruption and potential loss of system availability.

Recommendation

It is recommended to immediately update the Linux kernel to version 2.6.16.18 or later, which includes a fix for this vulnerability.
