CVE-2004-1137
Linux kernel 2.4.22-2.4.28 and 2.6.x-2.6.9 - Denial of Service and Remote Code Execution via IGMP Functionality
Title source: llmExploitation Summary
EIP tracks 1 public exploit for CVE-2004-1137. PoCs published by Paul Starzetz.
AI-analyzed exploit summary This exploit triggers a local denial-of-service (DoS) in Linux kernels by manipulating IGMP source filtering via repeated `IP_UNBLOCK_SOURCE` operations, causing a kernel crash. It leverages improper handling of source filter counts in the `igmp.c` implementation.
Description
Multiple vulnerabilities in the IGMP functionality for Linux kernel 2.4.22 to 2.4.28, and 2.6.x to 2.6.9, allow local and remote attackers to cause a denial of service or execute arbitrary code via (1) the ip_mc_source function, which decrements a counter to -1, or (2) the igmp_marksources function, which does not properly validate IGMP message parameters and performs an out-of-bounds read.
