Hi, The following vulnerability was published for net-tools. CVE-2025-46836[0]: | net-tools is a collection of programs that form the base set of the | NET-3 networking distribution for the Linux operating system. Inn | versions up to and including 2.10, the Linux network utilities (like | ifconfig) from the net-tools package do not properly validate the | structure of /proc files when showing interfaces. `get_name()` in | `interface.c` copies interface labels from `/proc/net/dev` into a | fixed 16-byte stack buffer without bounds checking, leading to | possible arbitrary code execution or crash. The known attack path | does not require privilege but also does not provide privilege | escalation in this scenario. A patch is available and expected to be | part of version 2.20. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
