If you do ls -l /proc/*/mem, and any of those have the same group as you, and have group readability, then you can read them. I assume there's no way of allowing everyone to read a processes memory. Incidentally, some of my /proc/*/mem files are mode 000. Is this a result of mlock(2), or is it a different function/syscall that's done that? -- PGP Key: D2729A3F - Keyserver: wwwkeys.uk.pgp.net - rich at rdrose dot org Key fingerprint = 5EB1 4C63 9FAD D87B 854C 3DED 1408 ED77 D272 9A3F Public key also encoded with outguess on http://rikrose.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
