Executable permissions

Is there a reason that the audit tools that take a file name paramater (-if) are not executable by non-root users? This prevents their use by an admin to do analysis of saved audit logs with an unprivileged user login.

Thanks - Karl

Current tools do not.

[root src]# grep getuid *.c

auditctl.c:             if (getuid() != 0) {
auditctl.c:             if (getuid() != 0) {

Must be root to send netlink

auditd.c: if (getuid() != 0) {

Must be root to read netlink

autrace.c: if (getuid() != 0) {

Must be root to write to netlink.

I think Karl is talking about the mode bits. The audit tools are 750, owned by root,root, on my system, so not executable by non-root users.

[root@localhost ~]# ls -l /sbin/au*

-rwxr-x--- 1 root root  68816 Dec  1 11:37 /sbin/autrace*

[root@localhost ~]# rpm -qa | grep audit
audit-libs-1.3-3.fc7
audit-1.3-3.fc7
audit-libs-python-1.3-3.fc7
audit-libs-devel-1.3-3.fc7

It's not the code, but rather the default permissions on the executables. So this might just be a packaging problem.

Thanks - Karl

Yeah, I think I can open it for those two programs.
