Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

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, read
uninitialized memory, obtain sensitive information, spoof the
addressbar contents, or execute arbitrary code. (CVE-2017-5470,

Multiple security issues were discovered in the Graphite 2 library
used by Firefox. If a user were tricked in to opening a specially
crafted website, an attacker could potentially exploit these to cause

code. (CVE-2017-7771, CVE-2017-7772, CVE-2017-7773, CVE-2017-7774,
CVE-2017-7775, CVE-2017-7776, CVE-2017-7777, CVE-2017-7778).

has attempted to automatically clean and format it as much as possible
without introducing additional issues.
