Request Tracker (RT) 4.x before 4.0.25, 4.2.x before 4.2.14, and 4.4.x before 4.4.2 does not use a constant-time comparison algorithm for secrets, which makes it easier for remote attackers to obtain sensitive user password information via a timing side-channel attack.

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.
