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-2023-25742) - Mozilla developers Philipp and Gabriele Svelto reported memory safety bugs present in Thunderbird 102.7. (CVE-2023-25739) - When importing a SPKI RSA public key as ECDSA P-256, the key would be handled incorrectly causing the tab to crash. (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 ScriptLoadContext. (CVE-2023-25735) - An invalid downcast from nsTextNode to SVGElement could have lead to undefined behavior. (CVE-2023-25732) - 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-2023-25730) - When 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-2023-25729) - 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. This could lead to further malicious actions such as downloading files or interacting with software already installed on the system. (CVE-2023-0767) - Mozilla: Content security policy leak in violation reports using iframes (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. Mozilla: User Interface lockup with messages combining S/MIME and OpenPGP (CVE-2023-0616) - 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.
