What is CVSS?
CVSS, or Common Vulnerability Scoring System, is the result of the National Infrastructure Advisory Council’s effort to standardize a system of assessing the criticality of a vulnerability. This system offers an unbiased criticality score that customers can use to judge how critical a vulnerability is and plan accordingly. For more information, please visit the CVSS website.
What are the CVSS scoring metrics that have been used?
| Base Score | 7.2 |
| Related exploit range (AccessVector) | Local |
| Attack complexity (AccessComplexity) | Low |
| Level of authentication needed (Authentication) | None |
| Confidentiality impact | Complete |
| Integrity impact | Complete |
| Availability impact | Complete |
| Temporal Score | 5.6 |
| Availability of exploit (Exploitability) | Proof of concept code |
| Type of fix available (RemediationLevel) | Official fix |
| Level of verification that vulnerability exists (ReportConfidence) | Confirmed |
NOTE: CVSS version 2.0 was used to generate this score.

What have you done to resolve the issue?
We've released a set of patches and hotfixes to address this security flaw.
Where do I download the fix?
Download the fix from the Product Downloads site.
You will need to provide a valid grant number to initiate the download.
Where can I find a list of all Security Bulletins?
All Security Bulletins are published on our Knowledge Center. Security Bulletins are retired (removed) once a product is both End of Sale and End of Support (End of Life).
How do I report a product vulnerability to you?
If you have information about a security issue or vulnerability with a product, follow the instructions provided in KB95563 - Report a vulnerability.
How do you respond to this and any other reported security flaws?
Our key priority is the security of our customers. If a vulnerability is found within any of our software or services, we work closely with the relevant security software development team to ensure the rapid and effective development of a fix and communication plan.
We only publish Security Bulletins if they include something actionable such as a workaround, mitigation, version update, or hotfix. Otherwise, we would simply be informing the hacker community that our products are a target, putting our customers at greater risk. For products that are updated automatically, a non-actionable Security Bulletin might be published to acknowledge the discoverer.
To view our PSIRT policy, see KB95564 - About PSIRT.
