VULHUB ™

The Linux kernel is a freely available, open source kernel originally written by Linus Torvalds. It is the core of all Linux distributions. A potential security risk has been reported in some versions of the Linux Kernel. The ifconfig utility may be used to determine the state of a network interface. Under some conditions, however, ifconfig may fail to report a network interface that is running in promiscuous mode. This may be the result of the kernel supporting multiple interfaces to the network device, allowing inconsistent behavior. Exploitation of this vulnerability may allow a malicious local user to disguise some activities. Network interfaces may be placed in promiscuous mode without detection by an administrator, possibly allowing a compromised machine to view internal network traffic.
