FREQUENTLY ASKED QUESTIONS


WHY IS RED HAT'S CVSS V3 SCORE OR IMPACT DIFFERENT FROM OTHER VENDORS?

For open source software shipped by multiple vendors, the CVSS base scores may
vary for each vendor's version depending on the version they ship, how they ship
it, the platform, and even how the software is compiled. This makes scoring of
vulnerabilities difficult for third-party vulnerability databases such as NVD
that only provide a single CVSS base score for each vulnerability. Red Hat
scores reflect how a vulnerability affects our products specifically.

For more information, see https://access.redhat.com/solutions/762393.


MY PRODUCT IS LISTED AS "UNDER INVESTIGATION" OR "AFFECTED", WHEN WILL RED HAT
RELEASE A FIX FOR THIS VULNERABILITY?

 * "Under investigation" doesn't necessarily mean that the product is affected
   by this vulnerability. It only means that our Analysis Team is still working
   on determining whether the product is affected and how it is affected.
 * "Affected" means that our Analysis Team has determined that this product is
   affected by this vulnerability and might release a fix to address this in the
   near future.


WHAT CAN I DO IF MY PRODUCT IS LISTED AS "WILL NOT FIX"?

This depends mostly on the Impact of the vulnerability and the Life Cycle phase
in which your product is currently in. Overall, you have the following options:
 * Upgrade to a supported product version that includes a fix for this
   vulnerability (recommended)
 * Apply a mitigation (if one exists)
 * Open a support case to request a prioritization of releasing a fix for this
   vulnerability


WHY IS MY SECURITY SCANNER REPORTING MY PRODUCT AS VULNERABLE TO THIS
VULNERABILITY EVEN THOUGH MY PRODUCT VERSION IS FIXED OR NOT AFFECTED?

In order to maintain code stability and compatibility, Red Hat usually does not
rebase packages to entirely new versions. Instead, we backport fixes and new
features to an older version of the package we distribute. This can result in
some security scanners that only consider the package version to report the
package as vulnerable. To avoid this, we suggest that you use an OVAL-compatible
security scanner like OpenSCAP.
