Note from the SUSE Security Team on the binutils package

SUSE considers binutils a developer tool which does not receive untrusted input. Code processed by binutils is being executed in any normal scenario, so security exploits could just inject regular binary code. For this reason we update binutils only around once a year to the current stable version to catch up on features and bugfixes. If you are processing untrusted binary code with binutils we recommend doing so on a seperate system or VM.
