-----BEGIN PGP SIGNED MESSAGE-----
Bugzilla is a Web-based bug-tracking system used by a large number of
software projects. The following security issues have been discovered
* The login form had no CSRF protection, meaning that an attacker could
force the victim to log in using the attacker's credentials.
* Dangerous control characters can be inserted into Bugzilla, notably
into bug comments, which can then be used to execute local commands.
All affected installations are encouraged to upgrade as soon as
Class: Cross-Site Request Forgery
Versions: Bugzilla 2.0 to 4.4.2, 4.5.1 to 4.5.2
Fixed In: 4.4.3, 4.5.3
Description: The login form had no CSRF protection, meaning that
an attacker could force the victim to log in using the
attacker's credentials. If the victim then reports a new
security sensitive bug, the attacker would get immediate
access to this bug.
Due to changes involved in the Bugzilla API, this fix is
not backported to the 4.0 and 4.2 branches, meaning that
Bugzilla 4.0.12 and older, and 4.2.8 and older, will
remain vulnerable to this issue.
CVE Number: CVE-2014-1517
Class: Social Engineering
Versions: Bugzilla 2.0 to 4.0.11, 4.1.1 to 4.2.7, 4.3.1 to 4.4.2,
4.5.1 to 4.5.2
Fixed In: 4.0.12, 4.2.8, 4.4.3, 4.5.3
Description: Dangerous control characters can be inserted into
Bugzilla, notably into bug comments. If the text, which
may look safe, is copied into a terminal such as xterm or
gnome-terminal, then unexpected commands could be executed
on the local machine.
CVE Number: none
The fixes for these issues are included in the 4.0.12, 4.2.8, 4.4.3
