Bugzilla: Multiple vulnerabilities — GLSA 200709-18

Bugzilla contains several vulnerabilities, some of them possibly leading to the remote execution of arbitrary code.

Affected Packages

www-apps/bugzilla on all architectures
Affected versions < 3.0.1
Unaffected versions revision >= 2.20.5, revision >= 2.22.3, >= 3.0.1, revision >= 2.22.5, revision >= 2.20.6

Background

Bugzilla is a web application designed to help with managing software development.

Description

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).

Impact

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

There is no known workaround at this time.

Resolution

All Bugzilla users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose www-apps/bugzilla
