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 via application
crash, denial of service via successive FTP authorization prompts or modal
alerts, trick the user with confusing permission request prompts, obtain
sensitive information, conduct social engineering attacks, or execute
arbitrary code. (CVE-2019-9788, CVE-2019-9789, CVE-2019-9790,
CVE-2019-9791, CVE-2019-9792, CVE-2019-9795, CVE-2019-9796, CVE-2019-9797,

A mechanism was discovered that removes some bounds checking for string,
array, or typed array accesses if Spectre mitigations have been disabled.
If a user were tricked in to opening a specially crafted website with
Spectre mitigations disabled, an attacker could potentially exploit this
to cause a denial of service, or execute arbitrary code. (CVE-2019-9793)
It was discovered that Upgrade-Insecure-Requests was incorrectly enforced
for same-origin navigation. An attacker could potentially exploit this to
conduct machine-in-the-middle (MITM) attacks. (CVE-2019-9803)
