USN-3991-1: Firefox vulnerabilities
21 May 2019
firefox vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
o Ubuntu 19.04
o Ubuntu 18.10
o Ubuntu 18.04 LTS
o Ubuntu 16.04 LTS
Summary
Firefox could be made to crash or run programs as your login if it opened a
malicious website.
Software Description
o firefox - Mozilla Open Source web browser
Details
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 cause a denial of service, spoof the browser UI, trick the user in to
launching local executable binaries, obtain sensitive information, conduct
cross-site scripting (XSS) attacks, or execute arbitrary code. (CVE-2019-11691,
CVE-2019-11692, CVE-2019-11693, CVE-2019-11695, CVE-2019-11696, CVE-2019-11699,
CVE-2019-11701, CVE-2019-7317, CVE-2019-9800, CVE-2019-9814, CVE-2019-9817,
CVE-2019-9819, CVE-2019-9820, CVE-2019-9821)
It was discovered that pressing certain key combinations could bypass addon
installation prompt delays. If a user opened a specially crafted website, an
attacker could potentially exploit this to trick them in to installing a
malicious extension. (CVE-2019-11697)
It was discovered that history data could be exposed via drag and drop of
hyperlinks to and from bookmarks. If a user were tricked in to dragging a
specially crafted hyperlink to the bookmark toolbar or sidebar, and
subsequently back in to the web content area, an attacker could potentially
exploit this to obtain sensitive information. (CVE-2019-11698)
A type confusion bug was discovered with object groups and UnboxedObjects. If a
user were tricked in to opening a specially crafted website after enabling the
UnboxedObjects feature, an attacker could potentially exploit this to bypass
security checks. (CVE-2019-9816)

The problem can be corrected by updating your system to the following package
versions:
Ubuntu 19.04
firefox - 67.0+build2-0ubuntu0.19.04.1
