"Multiple vulnerabilities have been discovered in Request Tracker, an
extensible trouble-ticket tracking system. The Common Vulnerabilities
and Exposures project identifies the following problems :

  - CVE-2016-6127
    It was discovered that Request Tracker is vulnerable to
    a cross-site scripting (XSS) attack if an attacker
    uploads a malicious file with a certain content type.
    Installations which use the AlwaysDownloadAttachments
    config setting are unaffected by this flaw. The applied
    fix addresses all existant and future uploaded
    attachments.

  - CVE-2017-5361
    It was discovered that Request Tracker is vulnerable to
    timing side-channel attacks for user passwords.

  - CVE-2017-5943
    It was discovered that Request Tracker is prone to an
    information leak of cross-site request forgery (CSRF)
    verification tokens if a user is tricked into visiting a
    specially crafted URL by an attacker.

  - CVE-2017-5944
    It was discovered that Request Tracker is prone to a
    remote code execution vulnerability in the dashboard
    subscription interface. A privileged attacker can take
    advantage of this flaw through carefully-crafted saved
    search names to cause unexpected code to be executed.
    The applied fix addresses all existant and future saved
    searches.

Additionally to the above mentioned CVEs, this update workarounds
CVE-2015-7686 in Email::Address which could induce a denial of service
of Request Tracker itself."
