Masahiro Yamada found that from the 2.17.1 version, Bugzilla does not
properly sanitize the content of the "buildid" parameter when filing
bugs (CVE-2007-4543). The next two vulnerabilities only affect Bugzilla
2.23.3 or later, hence the stable Gentoo Portage tree does not contain
these two vulnerabilities: Loic Minier reported that the
"Email::Send::Sendmail()" function does not properly sanitise "from"
email information before sending it to the "-f" parameter of
/usr/sbin/sendmail (CVE-2007-4538), and Frederic Buclin discovered that
the XML-RPC interface does not correctly check permissions in the
time-tracking fields (CVE-2007-4539).
</p>
</description>
<impact type="high">
<p>
A remote attacker could trigger the "buildid" vulnerability by sending
a specially crafted form to Bugzilla, leading to a persistent XSS, thus
allowing for theft of credentials. With Bugzilla 2.23.3 or later, an
attacker could also execute arbitrary code with the permissions of the
web server by injecting a specially crafted "from" email address and
gain access to normally restricted time-tracking information through
the XML-RPC service.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Bugzilla users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose www-apps/bugzilla</code>
</resolution>
