1. Topic:

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

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 2.14.1:

Bugzilla allows remote attackers to display restricted products and
components via a direct HTTP request to queryhelp.cgi. (CAN-2002-0803)

Bugzilla, when configured to perform reverse DNS lookups, allows remote
attackers to bypass IP restrictions by connecting from a system with a
spoofed reverse DNS hostname. (CAN-2002-0804)

Bugzilla creates new directories with world-writable permissions and 
creates the params file with world-writable permissions, which allows local
users to modify the files and execute code. (CAN-2002-0805)
Bugzilla allows authenticated users with editing privileges to delete other
users by directly calling the editusers.cgi script with the "del" option.
(CAN-2002-0806)

Cross-site scripting vulnerabilities in Bugzilla could allow remote
attackers to execute scripts as other Bugzilla users via the full name (real
name) field, which is not properly quoted by editusers.cgi. (CAN-2002-0807)

Bugzilla, when performing a mass change, sets the groupset of all bugs to
the groupset of the first bug. This could inadvertently cause insecure
groupset permissions to be assigned to some bugs. (CAN-2002-0808)

Bugzilla does not properly handle URL-encoded field names that are
generated by some browsers, which could cause certain fields to appear to
be unset. This has the effect of removing group permissions on bugs when
buglist.cgi is provided with the encoded field names. (CAN-2002-0809)

Bugzilla directs error messages from the syncshadowdb command to the HTML
output, which could leak sensitive information, including plaintext
passwords, if syncshadowdb fails. (CAN-2002-0810)

Bugzilla may allow remote attackers to cause a denial of service or execute
certain queries via a SQL injection attack on the sort order parameter to
buglist.cgi. (CAN-2002-0811)

All users of Bugzilla are advised to upgrade to these errata packages
containing Bugzilla version 2.14.3 which is not vulnerable 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.

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.

5. RPMs required:

Red Hat Powertools 7.0:

SRPMS: 
ftp://updates.Red Hat.com/7.0/en/powertools/SRPMS/bugzilla-2.14.3-1.src.rpm

noarch: 
ftp://updates.Red Hat.com/7.0/en/powertools/noarch/bugzilla-2.14.3-1.noarch.rpm

Red Hat Powertools 7.1:

SRPMS: 
ftp://updates.Red Hat.com/7.1/en/powertools/SRPMS/bugzilla-2.14.3-1.src.rpm

noarch: 
ftp://updates.Red Hat.com/7.1/en/powertools/noarch/bugzilla-2.14.3-1.noarch.rpm



6. Verification:

MD5 sum                          Package Name
--------------------------------------------------------------------------
1cbb82931e8bac613e465cd71ded8340 7.0/en/powertools/SRPMS/bugzilla-2.14.3-1.src.rpm
3240ecaa87a0782b5b0675d7c3d245bf 7.0/en/powertools/noarch/bugzilla-2.14.3-1.noarch.rpm
1cbb82931e8bac613e465cd71ded8340 7.1/en/powertools/SRPMS/bugzilla-2.14.3-1.src.rpm
3240ecaa87a0782b5b0675d7c3d245bf 7.1/en/powertools/noarch/bugzilla-2.14.3-1.noarch.rpm


These packages are GPG signed by Red Hat, Inc. for security.  Our key
is available at:
     http://www.Red Hat.com/about/contact/pgpkey.html

You can verify each package with the following command:
    rpm --checksig  

If you only wish to verify that each package has not been corrupted or
tampered with, examine only the md5sum with the following command:
    rpm --checksig --nogpg
