Security update for net-tools

This update for net-tools fixes the following issues:

  • Fix stack buffer overflow in parse_hex (bsc#1248687, GHSA-h667-qrp8-gj58).
  • Fix stack-based buffer overflow in proc_gen_fmt (bsc#1248687, GHSA-w7jq-cmw2-cq59).
  • Avoid unsafe memcpy in ifconfig (bsc#1248687).
  • Prevent overflow in ax25 and netrom (bsc#1248687)
  • Keep possibility to enter long interface names, even if they are not accepted by the kernel, because it was always possible up to CVE-2025-46836 fix. But issue a warning about an interface name concatenation (bsc#1248410).

Описание

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.
