[ubuntu-hardened] fs: suid_dumpable=2 and a security issue (gain root privileges).

[daniel curtis]

Hello Mr Cook.

So, if mode '2' was fixed that is safe as-is now, it can be used instead of
mode '1', right? One more question: what's your opinion on
'fs.suid_dumpable'? It is better to set it to '0' or, according to above
information about fixed mode '2', it rather should be set to mode '2'?

Thank You for an answer. Best regards.
