Ubuntu 12.04 LTS / 14.04 LTS / 15.10 : thunderbird vulnerabilities (USN-2904-1) (SLOTH)

Ubuntu Security Notice (C) 2016 Canonical, Inc. / NASL script (C) 2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

Karthikeyan Bhargavan and Gaetan Leurent discovered that NSS
incorrectly allowed MD5 to be used for TLS 1.2 connections. If a
remote attacker were able to perform a man-in-the-middle attack, this
flaw could be exploited to view sensitive information. (CVE-2015-7575)

Yves Younan discovered that graphite2 incorrectly handled certain
malformed fonts. If a user were tricked into 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 arbitary code with the privileges of the user invoking
Thunderbird. (CVE-2016-1523)

Bob Clary, Christian Holler, Nils Ohlmeier, Gary Kwong, Jesse
Ruderman, Carsten Book, and Randell Jesup discovered multiple memory
safety issues in Thunderbird. If a user were tricked in to opening a
specially crafted website in a browsing context, an attacker could
potentially exploit these to cause a denial of service via application
crash, or execute arbitrary code with the privileges of the user
invoking Thunderbird. (CVE-2016-1930)

Aki Helin discovered a buffer overflow when rendering WebGL content in
some circumstances. 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 with the privileges of the user invoking
Thunderbird. (CVE-2016-1935).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected thunderbird package.
