[GLSA-200612-06] Mozilla Thunderbird: Multiple vulnerabilities

Vulnerability Assessment Summary
Mozilla Thunderbird: Multiple vulnerabilities

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200612-06
(Mozilla Thunderbird: Multiple vulnerabilities)

It has been identified that Mozilla Thunderbird improperly handles
Script objects while they are being executed, permiting them to be
modified during execution. JavaScript is disabled in Mozilla
Thunderbird by default. Mozilla Thunderbird has also been found to be
vulnerable to various potential buffer overflows. Lastly, the binary
release of Mozilla Thunderbird is vulnerable to a low exponent RSA
signature forgery issue because it is bundled with a vulnerable version
of NSS.

Impact

A possible hacker could entice a user to view a specially crafted email that
causes a buffer overflow and again executes arbitrary code or causes a
Denial of Service. A possible hacker could also entice a user to view an
email containing specially crafted JavaScript and execute arbitrary
code with the rights of the user running Mozilla Thunderbird. It is
important to note that JavaScript is off by default in Mozilla
Thunderbird, and enabling it is strongly discouraged. It is also
possible for a possible hacker to create SSL/TLS or email certificates that
would not be detected as invalid by the binary release of Mozilla
Thunderbird, raising the possibility for Man-in-the-Middle attacks.

Workaround

There is no known workaround at this time.
