Security Bulletin 18A10338
Security Bulletin 18A10338 (CVE-2018-19279) 11/9/2018
SEVERITY RATING: LOW
When ZoneCentral for Windows prior to version 6.1.2236 is used to encrypt local folders on a NTFS file system, some very small files (with a size below approximately 600 bytes) can briefly appear in clear text on the disk. These files are overwritten with their encrypted version after a short delay (less than 5 seconds).
On SSD disks, persistent portions in clear text may remain longer, depending on the disk firmware.
This problem does not apply to network shares or any other file systems than NTFS.
