[appsuite-announce] Open-Xchange releases OX Abuse Shield v2.6.2

[Open-Xchange App Suite Maintenance Announcements]

Dear Open-Xchange Customers and Partners,

Open-Xchange is pleased to announce the release of OX Abuse Shield v2.6.2.

OX Abuse Shield provides abuse-prevention for Web Applications (including Webmail), POP, and IMAP. It is integrated with both OX App Suite and OX Dovecot Pro to prevent login and authentication abuse as well as protecting against brute-force attacks.

The goal of OX Abuse Shield is to detect brute forcing of passwords across many servers, services and instances, as well as enforce policy for authentication and authorization. In order to support the real world, brute force detection policy can be tailored to deal with "bulk, but legitimate" users of your service, as well as botnet-wide slow-scans of passwords.

The new OX Abuse Shield v2.6.2 provides the following fix:

- Better error checking in blacklist loading to prevent deadlock
- Fix missing stub for setBlacklistIPRetMsg() Lua function
- Fix trackalert crash when schedules are used before global Lua state is initialized
- Return 401 with appropriate JSON instead of 404 when webserver ACL is used
- New --loglevel flag to control the log level of stdout logging
