New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 5.8
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200608-04 (Mozilla Thunderbird: Multiple vulnerabilities)
The following vulnerabilities have been reported:
Benjamin Smedberg discovered that chrome URLss could be made to reference remote files.
Developers in the Mozilla community looked for and fixed several crash bugs to improve the stability of Mozilla clients.
'shutdown' reports that cross-site scripting (XSS) attacks could be performed using the construct XPCNativeWrapper(window).Function(...), which created a function that appeared to belong to the window in question even after it had been navigated to the target site.
'shutdown' reports that scripts granting the UniversalBrowserRead privilege can leverage that into the equivalent of the far more powerful UniversalXPConnect since they are allowed to 'read' into a privileged context.
Igor Bukanov and shutdown found additional places where an untimely garbage collection could delete a temporary object that was in active use.
Georgi Guninski found potential integer overflow issues with long strings in the toSource() methods of the Object, Array and String objects as well as string function arguments.
A malicious page can hijack native DOM methods on a document object in another domain, which will run the attacker's script when called by the victim page.
Secunia Research has discovered a vulnerability which is caused due to an memory corruption error within the handling of simultaneously happening XPCOM events.
This leads to use of a deleted timer object.
These events could lead to the execution of arbitrary code, or the installation of malware on the user's computer.
There is no known workaround at this time.
