Description
Does the glibc library (CVE-2015-7547) vulnerability affects SRA devices?
Resolution
Buffer overflow vulnerability in glibc library (CVE-2015-7547) currently affects versions equal and prior to 8.1.0.1-11sv for SRA 4600/1600/Virtual Appliance and 8.0.0.4-25sv for SRA 4200/1200.
You can find more information about this vulnerability in the following links:
https://support.sonicwall.com/product-notification/187642?productName=SonicWall%20SRA%20Series
https://cve.mitre.org/cgi-bin/cvename.cgi?name=cve-2015-7547
In order to fix this issue the firmware must be upgraded to the firmware version 8.1.0.2-14sv or higher for the SRA 4600/1600/Virtual Appliance and 8.0.0.5-27sv for the SRA 4200/1200.
You can download the firmware from the www.mysonicwall.com website.
In order to upgrade the firmware on the physical appliances (SRA 4600/1600/4200/1200), please follow the KB article: https://www.sonicwall.com/en-us/support/knowledge-base/170502339501169
For the SRA Virtual Appliance, upgrading the firmware using the .sig file does not resolve the issue. In this case you must deploy a new OVA file. The following the steps describe the procedure to deploy a new OVA file:
- Export the settings from the old virtual appliance from “System” > “Settings” > “Export Settings…”.
- Make a note of the serial number and authentication code of the old virtual appliance. You can find these on the “System” > “Status” page.
- Power off the old virtual appliance.
- Deploy the new virtual appliance using the OVA file available from www.mysonicwall.com.
- Power on the new virtual appliance and configure the X0 interface using the CLI.
- Log into the new virtual appliance with the default administrator credentials and import your saved configuration settings from "System" > "Settings" > "Import Settings".
- In MySonicWall, click on the serial number of the old virtual appliance. On the Service Management page for it, click the "Delete" button to delete licensing for the old virtual appliance.
- Register the new virtual appliance using the same serial number and authentication code of the old virtual appliance.
