Bug ID: 211958
Summary: Boot overflows when reading loader.conf
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
There are some overflows when reading loader.conf, for example if you add a
line like:
autoboot aaaaaaaaa...
It will overflow a 256 byte buffer here:
https://github.com/freebsd/freebsd/blob/af3e10e5a78d3af8cef6088748978c6c612757f0/sys/boot/common/boot.c#L132
https://github.com/freebsd/freebsd/blob/7fc7d2ed6e06340ab861cd094a78db87215ecff3/sys/boot/common/commands.c#L36
This sprintf pattern into command_errbuf seems to be repeated a lot, and should
probably be replaced with slprintf.
