Changelog:
4.2.16
Security Updates
* One of RT's dependencies, the Perl module Email::Address, has a
denial of service vulnerability which could induce a denial of
service of RT itself. We recommend updating to Email::Address
version 1.912 or later. The Email::Address vulnerabilities are
assigned CVE-2015-7686 and CVE-2015-12558. CVE-2015-7686 was
addressed in RT with a previous update. Email::Address version
1.912 addresses both of these CVEs with updates directly in the
source module. Thanks to Ricardo Signes for helping us with these
updates.
* One of RT's dependencies, the Perl module Email::Address::List,
relies on and operates similarly to Email::Address and therefore
also has potential denial of service vulnerabilities. These
vulnerabilities are assigned CVE-2018-18898. We recommend
administrators install Email::Address::List version 0.06 or
later. Thanks to Lukas Kramer for reporting the issue and Alex
Vandiver for contributing fixes.
* An optional RT dependency, HTML::Gumbo, incorrectly escaped HTML
in some cases. Since RT relies on this module to escape HTML
content, it's possible this issue could allow malicious HTML to be
displayed in RT. For RT's using this optional module, we recommend
administrators install HTML::Gumbo version 0.18 or later. Thanks
to Ruslan Zakirov for updating this module.
* The version of jQuery used in RT 4.2 and 4.4 has a Cross-site
Scripting (XSS) vulnerability when using cross-domain Ajax
requests. This vulnerability is assigned CVE-2015-9251. RT does
not use this jQuery feature so it is not directly
vulnerable. jQuery version 1.12 no longer receives official
updates, however a fix was posted with recommendations for
applications to patch locally, so RT will follow this
recommendation and ship with a patched version.
4.2.15
General user UI
* Show the Ticket's Subject when modifying the ticket.
* Re-format RT/Config.pm so the `# loc` comment parses correctly.
Web Administration
* Stop wrapping ShowUser in <a> tags to avoid unnecessary nested links.
* When listing group members, sort by text-only representation of the
user, not HTML (I#30771)
* In the group admin page, stop pre-computing ShowUser.
* In shredder, check for both id and name mismatches when loading objects
* Retain scrip sort order in pagination links
Internals
* Cache OCFVs to improve performance searching for duplicates when adding
values.
* Remove unused dependencies on File::Copy and Carp.
* On Oracle, return the empty string instead of undef for Subject when it
has no value on a ticket.
* Handle alphabetic words in RT::Plugin::Version
Developer
* Avoid using $id in /Ticket/Display.html so callbacks can modify id in ARGS.
Documentation
* Mention the RT-Attach-Message: yes header in template docs.
* Fix incorrect path in portlet documentation.
Internationalization
* Many changes to refactor sections of RT's internationalization code.
4.2.14
Security
* RT 4.0.0 and above are vulnerable to an information leak of cross-site
request forgery (CSRF) verification tokens if a user visits a specific
URL crafted by an attacker. This vulnerability is assigned
CVE-2017-5943. It was discovered by a third-party security researcher.
* RT 4.0.0 and above are 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. This fix addresses all existant and future uploaded
attachments. This vulnerability is assigned CVE-2016-6127. This was
responsibly disclosed to us first by Scott Russo and the GE Application
Security Assessment Team.
* One of RT's dependencies, a Perl module named Email::Address, has a
denial of service vulnerability which could induce a denial of service
of RT itself. We recommend administrators install Email::Address version
1.908 or above, though we additionally provide a new workaround within
RT. The Email::Address vulnerability was assigned CVE-2015-7686. This
vulnerability's application to RT was brought to our attention by Pali
Rohár.
* RT 4.0.0 and above are vulnerable to timing side-channel attacks for
user passwords. By carefully measuring millions or billions of login
attempts, an attacker could crack a user's password even over the
internet. RT now uses a constant-time comparison algorithm for secrets
to thwart such attacks. This vulnerability is assigned CVE-2017-5361.
This was responsibly disclosed to us by Aaron Kondziela.
* RT's ExternalAuth feature is vulnerable to a similar timing side-channel
attack. Both RT 4.0/4.2 with the widely-deployed RT::Authen::ExternalAuth
extension, as well as the core ExternalAuth feature in RT 4.4 are
vulnerable. Installations which don't use ExternalAuth, or which use
ExternalAuth for LDAP/ActiveDirectory authentication, or which use
ExternalAuth for cookie-based authentication, are unaffected. Only
ExternalAuth in DBI (database) mode is vulnerable.
* RT 4.0.0 and above are potentially vulnerable to a remote code execution
attack in the dashboard subscription interface. A privileged attacker
can cause unexpected code to be executed through carefully-crafted saved
search names. Though we have not been able to demonstrate an actual
attack owing to other defenses in place, it could be possible. This fix
addresses all existant and future saved searches. This vulnerability is
assigned CVE-2017-5944. It was discovered by an internal security audit.
* RT 4.0.0 and above have misleading documentation which could reduce
system security. The RestrictLoginReferrer config setting (which has
security implications) was inconsistent with its implementation, which
checked for a slightly different variable name. RT will now check for the
incorrect name and produce an error message. This was responsibly
disclosed to us by Alex Vandiver.
