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 :

USN-3391-1 fixed vulnerabilities in Firefox. This update provides the
corresponding update for Ubufox.

Multiple security issues were discovered in Firefox. If a user were
tricked in to opening a specially crafted website, an attacker could
potentially exploit these to conduct cross-site scripting (XSS)
attacks, bypass sandbox restrictions, obtain sensitive information,
spoof the origin of modal alerts, bypass same origin restrictions,
read uninitialized memory, cause a denial of service via program crash
or hang, or execute arbitrary code. (CVE-2017-7753, CVE-2017-7779,

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.
