Background ========== Bugzilla is a web application designed to help with managing software development. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-apps/bugzilla < 3.0.1 *>= 2.20.5 *>= 2.22.3 >= 3.0.1 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 Frédéric 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 References ========== [ 1 ] CVE-2007-4538 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4538 [ 2 ] CVE-2007-4539 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4539 [ 3 ] CVE-2007-4543 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4543 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200709-18.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
