Description Marek Haicman 2016-12-13 16:31:51 UTC
Description of problem:
Rule xccdf_org.ssgproject.content_rule_mount_option_var_tmp_bind tries to check whether mount is binded or not by searching /etc/mtab for bind option.

For some time now, /etc/mtab reflects kernel view - that there is no difference between binded and not binded - thus bind is not mentioned there. 

Version-Release number of selected component (if applicable):
scap-security-guide-0.1.30-3.el7.noarch

How reproducible:
reliably

Steps to Reproduce:
1. 
2.
3.

Actual results:
rule check contents of /etc/mtab

Expected results:
rule utilize different approach (comparison of inodes?)

Note: Important part is binded.pass.sh scenario in this case - error is due to discrepancy between how scan and remediation are performed. See Bug 1463829
