    Several security issues have been fixed in otrs2, a well known trouble
    ticket system.
    
    CVE-2018-11563
    
        An attacker who is logged into OTRS as a customer can use the ticket
        overview screen to disclose internal article information of their
        customer tickets.
    
    CVE-2019-12746
    
        A user logged into OTRS as an agent might unknowingly disclose their
        session ID by sharing the link of an embedded ticket article with
        third parties. This identifier can be then potentially abused in
        order to impersonate the agent user.
    
    CVE-2019-13458
    
        An attacker who is logged into OTRS as an agent user with
        appropriate permissions can leverage OTRS tags in templates in order
        to disclose hashed user passwords.
    
    
    Due to an incomplete fix for CVE-2019-12248, viewing email attachments
    was no longer possible. This update correctly implements the new
    Ticket::Fronted::BlockLoadingRemoteContent option.
    
    
    For Debian 8 "Jessie", these problems have been fixed in version
    3.3.18-1+deb8u11.
    
    We recommend that you upgrade your otrs2 packages.
