What is CVE-2005-4618?

CVE-2005-4618 is a low-severity memory corruption vulnerability in Linux kernel, published on 5 Jan 2006. It can only be exploited from the same machine or local network, with no action from the victim.

Official description

Buffer overflow in sysctl in the Linux Kernel 2.6 before 2.6.15 allows local users to corrupt user memory and possibly cause a denial of service via a long string, which causes sysctl to write a zero byte outside the buffer. NOTE: since the sysctl is called from a userland program that provides the argument, this might not be a vulnerability, unless a legitimate user-assisted or setuid scenario can be identified.
