1. Topic:

A number of security-related bugs have been found in Bugzilla version 2.14. 

This security erratum updates Bugzilla to version 2.14.1.  Bugzilla 2.14.1
is a security update; patches from a number of security-related bugs which
have already been applied to the working source version 2.15 in CVS, have
been applied to Bugzilla 2.14 to create the new stable release 2.14.1. This
new version fixes several security issues discovered since version 2.14 was
released, which are too serious to wait for the upcoming 2.16 release.

2. Relevant releases/architectures:

Red Hat Powertools 7.0 - noarch

Red Hat Powertools 7.1 - noarch

3. Problem description:

Bugzilla is a bug-tracking system from mozilla.org.  A number of security
issues have been found in version 2.14.  This security erratum updates
Bugzilla found in Red Hat Linux 6.2, 7, and 7.1 to the 2.14.1 version,
which is not vulnerable to these issues.
  
Bugzilla user account hijacking exploits:

Bug 54901: If LDAP Authentication was being used, Bugzilla would allow you
to log in as anyone if you left the password blank.

Bug 108385: It was possible to add comments as someone else by editing the
HTML on the show_bug.cgi page before submitting the form.

Bug 108516: It was possible to file a bug as someone else by editing the
HTML on enter_bug.cgi before submitting the form.

Bugzilla account security:

Bug 102141: The Product popup menu on the show_bug form listed all
products, even if the user didn't have access to all of them. 

Bug 108821: If you had any blessgroupset privs (the ability to change only
specific privileges for other users), it was possible to change your own
groupset (privileges) by altering the page HTML before submitting on
editusers.cgi.

Untrusted variables:

Bug 98146: An untrusted variable was echoed back to user in the HTML output
if there was a login error while editing votes.

Arbitrary SQL execution:

Bug 108812: buglist.cgi had an undocumented parameter that allowed you to
pass arbitrary SQL for the "WHERE" part of a query.

Bug 108822: It was possible for a user to send arbitrary SQL by inserting
single quotes in the "mybugslink" field in the user preferences.

Bug 109679: buglist.cgi was not validating that the field names being
passed from the "boolean chart" query form were valid field names, thus
allowing arbitrary SQL to be inserted if you edited the HTML by hand before
submitting the form.

Bug 109690: long_list.cgi was not validating that the bug ID parameter was
actually a number, allowing arbitrary SQL to be inserted if you edited the
HTML by hand.

Complete bug reports for all security issues can be obtained by visiting
the URL:  http://bugzilla.mozilla.org/show_bug.cgi?id=XXXXX
where XXXXX should be replaced with a bug number as listed above.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the names CAN-2001-0007, CAN-2001-0008, CAN-2001-0009,
CAN-2001-0010, CAN-2001-0011 to these issues.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade.  Only those
RPMs which are currently installed will be updated.  Those RPMs which are
not installed but included in the list will not be updated.  Note that you
can also use wildcards (*.rpm) if your current directory *only* contains
the
desired RPMs.

If you are using Red Hat Linux 6.x, you need to install the perl-DBI and
perl-Chart packages the current version of bugzilla depends on, as well,
using the command "rpm -Uvh perl*rpm".

Please note that this update is also available via Red Hat Network.  Many
people find this an easier way to apply updates.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
