Description Bryan Totty 2016-02-03 21:14:24 UTC

Description of problem:
The com.redhat.rhsa-all.xml is reporting incorrect kernel vulnerability updates required.
In this test, a RHEL 6.7 system is used and RHEL 6.4 vulnerabilities are reported as needing to be addressed.

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

$ cat uname -a
Linux rhel64-ia-01 2.6.32-573.12.1.el6.x86_64 #1 SMP Mon Nov 23 12:55:32 EST 2015 x86_64 x86_64 x86_64 GNU/Linux

$ cat /etc/redhat-release 
Red Hat Enterprise Linux Workstation release 6.7 (Santiago)

openscap-1.0.10-3.el6.x86_64
openscap-scanner-1.0.10-3.el6.x86_64
openscap-utils-1.0.10-3.el6.x86_64


How reproducible:
Always.

Steps to Reproduce:

Reference URL- https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Security_Guide/sect-Practical_Examples.html#sect-Auditing_Security_Vulnerabilities_Example

1. yum install openscap-utils
2. wget http://www.redhat.com/security/data/oval/com.redhat.rhsa-all.xml
3. oscap oval eval --results rhsa-results-oval.xml --report oval-report.html com.redhat.rhsa-all.xml


Actual results:
33 kernel errors. When selecting the link that describes the error, it shows CVEs/Patches for RHEL 6.4 (kernel-2.6.32-358.69.1.el6.x86_64). In this test, we are running RHEL 6.7 (2.6.32-573.12.1.el6.x86_64)

Expected results:
Only relevant CVEs/Patches for the correct kernel.

Comment 5 Martin Preisler 2016-02-04 10:45:36 UTC

Is kernel-2.6.32-358.69.1.el6.x86_64 installed on the machine? The CVE scan will report vulnerabilities for all installed packages, not just the ones that are running or in use.

Comment 6 Šimon Lukašík 2016-02-04 12:16:34 UTC

Hello Bryan,

Thanks time you spent filing this bug. Please communicate the following
to the customer.

Based on the sos report, on the system there are three kernels packages
installed:

    kernel-2.6.32-358.el6.x86_64
    kernel-2.6.32-504.23.4.el6.x86_64
    kernel-2.6.32-573.12.1.el6.x86_64

The vulnerability scan looks for any package that is vulnerable and is installed on the system. Hence you have got reports for kernel-2.6.32-358.el6.x86_64. The rationale is that here is a risk that someone would boot to this kernel package.
