When encoding data from an <code>inputStream</code> in <code>xpcom</code> the size of the input being encoded was not correctly calculated potentially leading to an out of bounds memory write. This vulnerability affects Firefox < 110, Thunderbird < 102.8, and Firefox ESR < 102.8.

Permission prompts for opening external schemes were only shown for <code>ContentPrincipals</code> resulting in extensions being able to open them without user interaction via <code>ExpandedPrincipals</code>. This could lead to further malicious actions such as downloading files or interacting with software already installed on the system. This vulnerability affects Firefox < 110, Thunderbird < 102.8, and Firefox ESR < 102.8.

The return value from `gfx::SourceSurfaceSkia::Map()` wasn't being verified which could have potentially lead to a null pointer dereference. This vulnerability affects Firefox < 110.

An invalid downcast from <code>nsTextNode</code> to <code>SVGElement</code> could have lead to undefined behavior. This vulnerability affects Firefox < 110, Thunderbird < 102.8, and Firefox ESR < 102.8.

Mmemory safety bugs present in Firefox 109 and 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. This vulnerability affects Firefox < 110 and Firefox ESR < 102.8.

Members of the <code>DEVMODEW</code> struct set by the printer device driver weren't being validated and could have resulted in invalid values which in turn would cause the browser to attempt out of bounds access to related variables.<br>*This bug only affects Firefox on Windows. Other operating systems are unaffected.*. This vulnerability affects Firefox < 110, Thunderbird < 102.8, and Firefox ESR < 102.8.

When importing a SPKI RSA public key as ECDSA P-256, the key would be handled incorrectly causing the tab to crash. This vulnerability affects Firefox < 110, Thunderbird < 102.8, and Firefox ESR < 102.8.

Due to URL previews in the network panel of developer tools improperly storing URLs, query parameters could potentially be used to overwrite global objects in privileged code. This vulnerability affects Firefox < 110.
