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.redhat.com/7.0/en/powertools/SRPMS/bugzilla-2.14.3-1.src.rpm
noarch:
ftp://updates.redhat.com/7.0/en/powertools/noarch/bugzilla-2.14.3-1.noarch.rpm
Red Hat Powertools 7.1:
SRPMS:
ftp://updates.redhat.com/7.1/en/powertools/SRPMS/bugzilla-2.14.3-1.src.rpm
noarch:
ftp://updates.redhat.com/7.1/en/powertools/noarch/bugzilla-2.14.3-1.noarch.rpm
6. Verification:
MD5 sum Package Name

These packages are GPG signed by Red Hat, Inc. for security. Our key
is available at:
http://www.redhat.com/about/contact/pgpkey.html
You can verify each package with the following command:
rpm --checksig <filename>
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 <filename>
