Ubuntu Security Notice (C) 2017 Canonical, Inc. / NASL script (C) 2017 Tenable Network Security, Inc.


Synopsis :

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

Description :

Multiple security issues were discovered 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 bypass
same-origin restrictions, bypass CSP restrictions, obtain sensitive
information, spoof the origin of modal alerts, cause a denial of
service via application crash, or execute arbitrary code.
(CVE-2017-7753, CVE-2017-7779, CVE-2017-7784, CVE-2017-7785,
CVE-2017-7787, CVE-2017-7791, CVE-2017-7792, CVE-2017-7800,

A buffer overflow was discovered when displaying SVG content in some
circumstances. 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-2017-7786).

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.
