Submission + - MS Exchange Anti-Malware crashes due to year 2022 (bleepingcomputer.com)
Kalper writes: Bleeping Computer reports: "Microsoft Exchange on-premise servers cannot deliver email starting on January 1st, 2022, due to a "Year 2022" bug in the FIP-FS anti-malware scanning engine. ... Security researcher and Exchange admin Joseph Roosen said that this is caused by Microsoft using a signed int32 variable to store the value of a date, which has a maximum value of 2,147,483,647. However, dates in 2022 have a minimum value of 2,201,010,001 or larger, which is greater than the maximum value that can be stored in the signed int32 variable, causing the scanning engine to fail and not release mail for delivery."
