==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.10
- Ubuntu 16.04 LTS

- Ubuntu 12.04 LTS
Summary:
Several security issues were fixed in Thunderbird.
Software Description:
- thunderbird: Mozilla Open Source mail and newsgroup client
Details:
Christian Holler, Jon Coppeard, Olli Pettay, Ehsan Akhgari, Gary Kwong,
Tooru Fujisawa, and Randell Jesup discovered multiple memory safety issues
in Thunderbird. If a user were tricked in to opening a specially crafted
message, an attacker could potentially exploit these to cause a denial of
service via application crash, or execute arbitrary code. (CVE-2016-5290)
A same-origin policy bypass was discovered with local HTML files in some
circumstances. An attacker could potentially exploit this to obtain
sensitive information. (CVE-2016-5291)
A heap buffer-overflow was discovered in Cairo when processing SVG
content. If a user were tricked in to opening a specially crafted message,
an attacker could potentially exploit this to cause a denial of service
via application crash, or execute arbitrary code. (CVE-2016-5296)
An error was discovered in argument length checking in Javascript. If a
user were tricked in to opening a specially crafted website in a browsing
context, an attacker could potentially exploit this to cause a denial of
service via application crash, or execute arbitrary code. (CVE-2016-5297)
A buffer overflow was discovered in nsScriptLoadHandler. If a user were
tricked in to opening a specially crafted website in a browsing context,
an attacker could potentially exploit this to cause a denial of service
via application crash, or execute arbitrary code. (CVE-2016-9066)
A use-after-free was discovered in SVG animations. If a user were tricked
in to opening a specially crafted website in a browsing context, an
attacker could exploit this to cause a denial of service via application
crash, or execute arbitrary code. (CVE-2016-9079)
