Details

Multiple memory safety issues were discovered in Thunderbird. If the user
were tricked into opening a specially crafted message with scripting
enabled, an attacker could possibly exploit these to cause a denial of
service via application crash, or potentially execute arbitrary code with
the privileges of the user invoking Thunderbird. (CVE-2013-1682)

Abhishek Arya discovered multiple use-after-free bugs. If the user were
tricked into opening a specially crafted message with scripting enabled,
an attacker could possibly exploit these to execute arbitrary code with
the privileges of the user invoking Thunderbird. (CVE-2013-1684,
CVE-2013-1685, CVE-2013-1686)

Mariusz Mlynski discovered that user defined code within the XBL scope of
an element could be made to bypass System Only Wrappers (SOW). If a user
had scripting enabled, an attacker could potentially exploit this to
execute arbitrary code with the privileges of the user invoking
Thunderbird. (CVE-2013-1687)

A crash was discovered when reloading a page that contained content using
the onreadystatechange event. If a user had scripting enabled, an attacker
could potentially exploit this to execute arbitrary code with the
privileges of the user invoking Thunderbird. (CVE-2013-1690)

Johnathan Kuskos discovered that Thunderbird sent data in the body of
XMLHttpRequest HEAD requests. If a user had scripting enabled, an attacker
could exploit this to conduct Cross-Site Request Forgery (CSRF) attacks.
(CVE-2013-1692)

Paul Stone discovered a timing flaw in the processing of SVG images with
filters. If a user had scripting enabled, an attacker could exploit this
to view sensitive information. (CVE-2013-1693)

Boris Zbarsky discovered a flaw in PreserveWrapper. If a user had
scripting enabled, an attacker could potentially exploit this to cause
a denial of service via application crash, or execute code with the
privileges of the user invoking Thunderbird. (CVE-2013-1694)

It was discovered that XrayWrappers could be bypassed to call
content-defined methods in certain circumstances. If a user had scripting
enabled, an attacker could exploit this to cause undefined behaviour.
(CVE-2013-1697)
