Subject: Re: World Writable File in MQ Directory - Security issue


Any user needs to be able to create files in these directories in order for
the MQ code to work.   Is the issue that you are concerned about a DOS
attack where a malicious user does an rmdir?

The permissions I see on my Linux MQ 5.3 system for (most of) these
directories are:

drwxrwsrwx

So (for most)  the "sgid" bit is set, which means that files created in
these directories have a group owner of mqm.

However, the bit I was expecting to see set (and was not) was the "sticky
bit" which would prevent a normal user from removing the directory or files
in it they didn't create.

So I suspect that your concern may be valid.

Time for a "security/integrity" APAR?

PS The permissions on the /var/mqm/qmgrs/QMGR directories were drwxrwxr-x
and this should be OK!

Dave
