| Description: | Summary:
The remote host is missing an update for the 'firefox' package(s) announced via the USN-3991-1 advisory.
Vulnerability Insight:
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,

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

potentially exploit this to obtain sensitive information. (CVE-2019-11698)
A type confusion bug was discovered with object groups and UnboxedObjects.
