We have discovered security vulnerabilities which affect both RT 4.0.x
and RT 4.2.x. We are releasing RT versions 4.0.24 and 4.2.12 to resolve
these vulnerabilities, as well as patches which apply atop all released
versions of 4.0 and 4.2.

The vulnerabilities addressed by 4.0.24, 4.2.12, and the below patches
include the following:

RT 4.0.0 and above are vulnerable to a cross-site scripting (XSS) attack via
the user and group rights management pages. This vulnerability is assigned
CVE-2015-5475. It was discovered and reported by Marcin Kopeć at Data Reliance
Shared Service Center.

RT 4.2.0 and above are vulnerable to a cross-site scripting (XSS) attack
via the cryptography interface. This vulnerability could allow an attacker
with a carefully-crafted key to inject JavaScript into RT's user interface.
Installations which use neither GnuPG nor S/MIME are unaffected.

Patches for all releases of 4.0.x and 4.2.x are available for download
below. Versions of RT older than 4.0.0 are unsupported and do not
receive security patches; please contact sales@bestpractical.com if you
need assistance with an older RT version.
