GLSA 200709-18: Bugzilla: Multiple vulnerabilities

http://security.gentoo.org/

Severity:	high
Title:	Bugzilla: Multiple vulnerabilities
Date:	09/30/2007
Bugs:	#190112
ID:	200709-18

Synopsis

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

Background

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

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
www-apps/bugzilla	< 3.0.1	>= 2.20.5	All supported architectures

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
