net-tools Stack-based Buffer Overflow vulnerability

net-tools is a collection of programs that form the base set of the NET-3networking distribution for the Linux operating system. Inn versions up toand including 2.10, the Linux network utilities (like ifconfig) from thenet-tools package do not properly validate the structure of /proc fileswhen showing interfaces. `get_name()` in `interface.c` copies interfacelabels from `/proc/net/dev` into a fixed 16-byte stack buffer withoutbounds checking, leading to possible arbitrary code execution or crash. Theknown attack path does not require privilege but also does not provideprivilege escalation in this scenario. A patch is available and expected tobe part of version 2.20.
