Notes

Security: Security warning - Z-Push ActiveSync Clients

A security hole in our implementation of Z-Push into the Collax authentication system may allow unauthorized access to Kopano’s email accounts. This vulnerability affects all Collax installations using Kopano and the Collax version 7 Z-Push module. With the release version 7.0.14 the bug has been fixed. The update includes a current z-push and a new z-push web services package as well as a system library. The vulnerability is classified as critical. Please update all Collax server systems accordingly on which Kopano and Z-Push are used.

E-Mail: Increased required space when using IMAP and full-text index

The option “Generate full-text index” in the options of the dialog “Mail and Messaging -> Mail Storage -> IMAP and POP3” generates a full-text index of the local IMAP folders which accelerates the search within the IMAP folders and e-mails. While activated, the system could use up to 20% more space compared to the former release (also with activated index) for the service cyrus. Please check the space requirements of the service cyrus in advance. Under the dialog “Status -> System -> Statistics” the graph “filesystem/data” shows further details.

System Management: Monitoring Media Erros on LSI Controllers

Within this update the active monitoring of media errors on LSI RAID-Controllers has been customized. Up to now a warning information for hard disks with a single media error has been issued, although the controller was able to handle those errors and correct them automatically. From now on the warning threshold is 100 errors.
