     CVE-2023-25744,
     CVE-2023-25746

An attacker could construct a PKCS 12 cert bundle in such a way that could
allow for arbitrary memory writes via PKCS 12 Safe Bag attributes being
mishandled (CVE-2023-0767).

The Content-Security-Policy-Report-Only header could allow an attacker to leak
a child iframe's unredacted URI when interaction with that iframe triggers a
redirect (CVE-2023-25728).

Permission prompts for opening external schemes were only shown for
ContentPrincipals resulting in extensions being able to open them without user
interaction via ExpandedPrincipals. This could lead to further malicious
actions such as downloading files or interacting with software already
installed on the system (CVE-2023-25729).

A background script invoking requestFullscreen and then blocking the main
thread could force the browser into fullscreen mode indefinitely, resulting in
potential user confusion or spoofing attacks (CVE-2023-25730).

In EncodeInputStream, wen encoding data from an inputStream in xpcom the size
of the input being encoded was not correctly calculated potentially leading
to an out of bounds memory write (CVE-2023-25732).

In SpiderMonkey, cross-compartment wrappers wrapping a scripted proxy could
have caused objects from other compartments to be stored in the main
compartment resulting in a use-after-free after unwrapping the proxy
(CVE-2023-25735).

An invalid downcast from nsTextNode to SVGElement in
SVGUtils::SetupStrokeGeometry could have lead to undefined behavior
(CVE-2023-25737).

Module load requests that failed were not being checked as to whether or not
they were cancelled causing a use-after-free in
mozilla::dom::ScriptLoadContext::~ScriptLoadContext (CVE-2023-25739).

In Web Crypto, when importing a SPKI RSA public key as ECDSA P-256, the key
would be handled incorrectly causing the tab to crash (CVE-2023-25742).

Mozilla developers Philipp and Gabriele Svelto, Kershaw Chang, and the Mozilla
Fuzzing Team reported memory safety bugs present in Firefox ESR 102.7. Some of
these bugs showed evidence of memory corruption and we presume that with
enough effort some of these could have been exploited to run arbitrary code
(CVE-2023-25744, CVE-2023-25746).
