Ubuntu Security Notice (C) 2017 Canonical, Inc. / NASL script (C) 2017 Tenable Network Security, Inc.
The remote Ubuntu host is missing a security-related patch.
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 read uninitialized memory, obtain
sensitive information, bypass phishing and malware protection, spoof
the origin in modal dialogs, conduct cross-site scripting (XSS)
attacks, cause a denial of service via application crash, or execute
arbitrary code. (CVE-2017-7793, CVE-2017-7810, CVE-2017-7811,
CVE-2017-7812, CVE-2017-7813, CVE-2017-7814, CVE-2017-7815,
CVE-2017-7818, CVE-2017-7819, CVE-2017-7820, CVE-2017-7822,
Martin Thomson discovered that NSS incorrectly generated handshake
hashes. A remote attacker could potentially exploit this to cause a
denial of service via application crash, or execute arbitrary code.
Multiple security issues were discovered in WebExtensions. If a user
were tricked in to installing a specially crafted extension, an
attacker could potentially exploit these to download and open
non-executable files without interaction, or obtain elevated
privileges. (CVE-2017-7816, CVE-2017-7821).
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.
Update the affected firefox package.
