Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D
Bugzilla contains several vulnerabilities, some of them possibly
leading to the remote execution of arbitrary code.
Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Bugzilla is a web application designed to help with managing software
development.
Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-apps/bugzilla < 3.0.1 *>=3D 2.20.5
*>=3D 2.22.3
>=3D 3.0.1
Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
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 Fr=E9d=E9ric Buclin discovered
that the XML-RPC interface does not correctly check permissions in the
time-tracking fields (CVE-2007-4539).
Impact
=3D=3D=3D=3D=3D=3D
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.
Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
There is no known workaround at this time.
Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
All Bugzilla users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose www-apps/bugzilla
