The remote host is missing an update for the 'firefox'
Linux Distribution Package(s) announced via the USN-4122-1 advisory.
Checks if a vulnerable Linux Distribution Package version is present on the target host.
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 obtain sensitive information, bypass
Content Security Policy (CSP) protections, bypass same-origin
restrictions, conduct cross-site scripting (XSS) attacks, cause a denial
of service, or execute arbitrary code. (CVE-2019-5849, CVE-2019-11734,
CVE-2019-11735, CVE-2019-11737, CVE-2019-11738, CVE-2019-11740,
CVE-2019-11742, CVE-2019-11743, CVE-2019-11744, CVE-2019-11746,
CVE-2019-11748, CVE-2019-11749, CVE-2019-11750, CVE-2019-11752)
It was discovered that a compromised content process could log in to a
malicious Firefox Sync account. An attacker could potentially exploit
this, in combination with another vulnerability, to disable the sandbox.
It was discovered that addons.mozilla.org and accounts.firefox.com could
be loaded in to the same content process. An attacker could potentially
exploit this, in combination with another vulnerability that allowed a
cross-site scripting (XSS) attack, to modify browser settings.
It was discovered that the 'Forget about this site' feature in the
history pane removes HTTP Strict Transport Security (HSTS) settings for
sites on the pre-load list. An attacker could potentially exploit this
to bypass the protections offered by HSTS. (CVE-2019-11747)
