Ubuntu 10.04 LTS / 11.10 / 12.04 LTS / 12.10 : thunderbird vulnerabilities (USN-1748-1)

Ubuntu Security Notice (C) 2013 Canonical, Inc. / NASL script (C) 2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

Bobby Holley discovered vulnerabilities in Chrome Object Wrappers
(COW) and System Only Wrappers (SOW). If a user were tricked into
opening a specially crafted page and had scripting enabled, a remote
attacker could exploit this to bypass security protections to obtain
sensitive information or potentially execute code with the privileges
of the user invoking Thunderbird. (CVE-2013-0773)

Frederik Braun discovered that Thunderbird made the location of the
active browser profile available to JavaScript workers. Scripting for
Thunderbird is disabled by default in Ubuntu. (CVE-2013-0774)

A use-after-free vulnerability was discovered in Thunderbird. An
attacker could potentially exploit this to execute code with the
privileges of the user invoking Thunderbird if scripting were enabled.
(CVE-2013-0775)

Michal Zalewski discovered that Thunderbird would not always show the
correct address when cancelling a proxy authentication prompt. A
remote attacker could exploit this to conduct URL spoofing and
phishing attacks if scripting were enabled. (CVE-2013-0776)

Abhishek Arya discovered several problems related to memory handling.
If the user were tricked into opening a specially crafted page, an
attacker could possibly exploit these to cause a denial of service via
application crash, or potentially execute code with the privileges of
the user invoking Thunderbird. (CVE-2013-0777, CVE-2013-0778,
CVE-2013-0779, CVE-2013-0780, CVE-2013-0781, CVE-2013-0782)

Olli Pettay, Christoph Diehl, Gary Kwong, Jesse Ruderman, Andrew
McCreight, Joe Drew, Wayne Mery, Alon Zakai, Christian Holler, Gary
Kwong, Luke Wagner, Terrence Cole, Timothy Nikkel, Bill McCloskey, and
Nicolas Pierron discovered multiple memory safety issues affecting
Thunderbird. If a user had scripting enabled and was tricked into
opening a specially crafted page, an attacker could possibly exploit
these to cause a denial of service via application crash.
(CVE-2013-0783, CVE-2013-0784).
