"USN-3391-1 fixed vulnerabilities in Firefox. This update provides the
corresponding update for Ubufox.

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 conduct cross-site scripting (XSS)
attacks, bypass sandbox restrictions, obtain sensitive information,
spoof the origin of modal alerts, bypass same origin restrictions,
read uninitialized memory, cause a denial of service via program crash
or hang, or execute arbitrary code. (CVE-2017-7753, CVE-2017-7779,
