CVE-2011-2534
Published: 22 June 2011
Buffer overflow in the clusterip_proc_write function in net/ipv4/netfilter/ipt_CLUSTERIP.c in the Linux kernel before 2.6.39 might allow local users to cause a denial of service or have unspecified other impact via a crafted write operation, related to string data that lacks a terminating '\0' character.
From the Ubuntu security team
Vasiliy Kulikov discovered that the netfilter code did not check certain strings copied from userspace. A local attacker with netfilter access could exploit this to read kernel memory or crash the system, leading to a denial of service.
