frame-attach operations from occurring during or after frame-detach
operations. If a user were tricked in to opening a specially crafted
website, an attacker could potentially exploit this to bypass
same-origin restrictions. (CVE-2016-1623)

An integer underflow was discovered in Brotli. If a user were tricked
in to opening a specially crafted website, an attacker could
potentially exploit this to cause a denial of service via application
crash, or execute arbitrary code with the privileges of the user
invoking the program. (CVE-2016-1624).

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
