Linux Kernel IGMP Multiple Vulnerabilities

Linux kernel IGMP functionality is reported prone to multiple vulnerabilities. These issues can allow local attackers to carry out denial of service and privilege escalation attacks. Remote attackers may also cause denial of service conditions in vulnerable computers.

The first issue exists in the 'ip_mc_source()' function and may allow local attackers to cause a denial of service condition or gain elevated privileges.

The second issue is related to the first issue and may allow an attacker to disclose sensitive kernel memory.

The third vulnerability exists in the IGMP/IP networking module and may allow remote attackers to cause a denial of service condition in a vulnerable computer.
