Disable kernel support for MISC binaries
Medium Severity
Enabling
CONFIG_BINFMT_MISC
makes it possible to plug wrapper-driven binary formats into the kernel. This is specially useful for programs that need an interpreter to run like Java, Python and DOS emulators. Once you have registered such a binary class with the kernel, you can start one of those programs simply by typing in its name at a shell prompt. The configuration that was used to build kernel is available at
/boot/config-*
. To check the configuration value for
CONFIG_BINFMT_MISC
, run the following command:
grep CONFIG_BINFMT_MISC /boot/config-*
Configs with value 'n' are not explicitly set in the file, so either commented lines or no lines should be returned.
