The remote host is affected by the vulnerability described in GLSA-200709-18 (Bugzilla: Multiple vulnerabilities)
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.
