SonicWall was a victim of the Microsoft Y2K22 Exchange Server bug too, fixes released

Y2K22 Exchange server bug

Firewall and various other cyber-security solutions provider SonicWall has released patches that fix the problems related to the recent Microsoft Y2K22 Exchange Server bug that was causing an enormous email jam.

The cyber-security firm has noted the following issues that its administrators and general users of its Email security products were facing during the Y2K22 crisis:

  • Inability to access junk box or un-junk new emails
  • Inability to trace the incoming/outgoing emails through message logs

The following patches have been released by SonicWall to resolve those problems:

  • Hosted Email Security: FULLY PATCHED – The fix was deployed in North America and Europe instances on Jan. 2. No action is needed from Hosted Email Security customers.

  • Email Security Appliance: FIX RELEASED – ES 10.0.15 is available for download via mysonicwall.com. Customers using Email Security Appliance (On-Prem) should upgrade their firmware to ES 10.0.15. Upgrade to ES 10.0.15 will automatically start the database rebuild and the process can take a few hours to complete depending on the amount of data. Junk Box emails and Message Logs will be displayed accurately after the database is fully rebuilt. Please refer to the knowledge base (KB) article for guidance on firmware upgrade.

  • Firewall Anti-Spam Junk Store: FIX RELEASED – Customers using Anti-Spam Junk Store functionality on firewalls running SonicOS 6.x should upgrade to the latest Junk Store 7.6.9. Junk Store 7.6.9 installer is posted under SonicOS 6.5.x firmware in MySonicWall downloads section for TZ, NSA and SOHO platforms. Customers using SonicOS 7.x on any platform are not impacted.

The Y2K22 error was a massive date processing failure issue as the new value chosen "2.201.010.001" exceeds what the Servers are capable of processing under the current Int32 data type. As a result, the malware checking engine was crashing, and consequently, emails and messages have been stuck in transport queues across Exchange Servers 2016 and 2019 with Application event log errors 5300 and 1106 (FIPFS).
