Recommended Patches, Late-Breaking Issues

Note: Mirapoint's policy is to always integrate patches created to address known problems into the next patch release.

Addressbook

• Exporting contacts as a CSV file using the Firefox browser in a non-English locale would fail. (MIRA-55346)

Administration

• Accidentally entering a space character on the end of a domain in 'ldap gui' mode when administering a domain could result in all ldap entries for that domain being removed. (MIRA-55314)
• Rebuilding a mailbox with more than 150,000 messages would fail with an 'out of memory' error. Mailbox rebuilds could only be conducted by the Support team. (MIRA-55115)
• Restoring a delegated domain user via a selective restore may restore the user to the incorrect domain. (MIRA-55272)
• Deleting a user could fail after selectively restoring an entire domain. (MIRA-55315)

Calendar

• In some cases, a user could not see all events of a user on a different host even though they had been granted permission. (MIRA-55359)

Clustering

• The N+1 failover subsystem, could occasionally, inaccurately determine a network failure and cause a failover that is not required. (MIRA-55383)

Documentation

• Very long message subjects encoded using ISO-2022-JP could cause the filtering subsystem to crash. (MIRA-55405)

IMAP

• Logging in as 'administrator' when the IMAP server is in 'ldapproxy' mode no longer causes the session to hang or terminate. (MIRA-55156)
• A large number of IMAP search parameters would cause excessive load and could crash the IMAP service. IMAP search parameters are now limited to a maximum of 200. (MIRA-55401)

• The command 'storage listsan' could fail with the error message 'unexpected command result = 11', if there were a higher number of valid paths to a LUN. (MIRA-55356)

Webmail

• Implemented a timeout in which all HTTP request headers and bodies must be received in to avoid the slow HTTP header attack vulnerability. Header timeout: 10 seconds; Body timeout: 30 seconds. (MIRA-55387)
