Description of problem:

I have scan results on my Atomic Host system. The Atomic Scan DBus API now hangs when I try to access vulnerability info via the DBus API.

Version-Release number of selected component (if applicable):

# rpm -q atomic
atomic-1.14.1-1.fc25.x86_64

How reproducible:

Every time.

Steps to Reproduce:

# mkdir -p /var/lib/atomic/atomic_scan_openscap/2016-12-11-12-09-57-674487/7968321274dc6b6171697c33df7815310468e694ac5be0ec03ff053bb135e768/

# printf '{"Scanner": "openscap", "Scan Type": "Standard Compliance", "Vulnerabilities": [{"Custom": {"XCCDF result": "fail"}, "Severity": "Low", "Description": "\nThe RPM package management system can check file access\npermissions of installed software packages, including many that are\nimportant to system security. \nAfter locating a file with incorrect permissions, run the following command to determine which package owns it:\n", "Title": "Verify and Correct File Permissions with RPM"}, {"Custom": {"XCCDF result": "fail"}, "Severity": "Moderate", "Description": "\nSystem executables are stored in the following directories by default:\n", "Title": "Verify that System Executables Have Restrictive Permissions"}], "Successful": "true", "Finished Time": "2016-12-11T12:10:27", "Time": "2016-12-11T12:09:59", "UUID": "/scanin/d6fe5fdc49c2886ccad1c781d38a0c9fe679c6e7ca0297d23186c385873e86fa"}' > /var/lib/atomic/atomic_scan_openscap/2016-12-11-12-09-57-674487/7968321274dc6b6171697c33df7815310468e694ac5be0ec03ff053bb135e768/json

# gdbus call --system --dest org.atomic --object-path /org/atomic/object --method org.atomic.VulnerableInfo

Actual results:

The DBus API hangs until it times out:

Error: Timeout was reached


Expected results:

A real reply from the DBus API:

('{"7968321274dc6b6171697c33df7815310468e694ac5be0ec03ff053bb135e768": {"UUID": "7968321274dc6b6171697c33df7815310468e694ac5be0ec03ff053bb135e768", "Scan Type": "Standards Compliance", "json_file": "/var/lib/atomic/atomic_scan_openscap/2016-12-11-12-09-57-674487/7968321274dc6b6171697c33df7815310468e694ac5be0ec03ff053bb135e768/json", "Time": "2016-12-11T12:09:59", "Vulnerable": true, "Scanner": "openscap"}}\n',)
