o Ubuntu 14.04 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, or execute arbitrary code. (CVE-2018-12375,
CVE-2018-12376, CVE-2018-12377, CVE-2018-12378)
It was discovered that if a user saved passwords before Firefox 58 and then
later set a master password, an unencrypted copy of these passwords would still
be accessible. A local user could exploit this to obtain sensitive information.
(CVE-2018-12383)
