CVE-2006-2444

Linux Kernel < 2.6.16.18 - Denial of Service via SNMP Trap Decode Failure

Title source: llm

Exploitation Summary

EIP tracks 1 public exploit for CVE-2006-2444. PoCs published by ECL Labs.

AI-analyzed exploit summary This exploit targets CVE-2006-2444, a vulnerability in the Netfilter NAT SNMP module in Linux kernels before 2.6.16.18. It crafts a malformed SNMP packet to trigger a denial-of-service condition by exploiting improper handling in snmp_parse_mangle() and snmp_trap_decode().

Description

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.
