CVE-2022-45403: Service Workers might have learned size of cross-origin media files

Reporter

Anne van Kesteren and Karl Tomlinson

Impact

high

Description

Service Workers should not be able to infer information about opaque cross-origin responses; but timing information for cross-origin media combined with Range requests might have allowed them to determine the presence or length of a media file. References

Reporter

Impact

high

Description

Through a series of popup and window.print() calls, an attacker can cause a window to go fullscreen without the user seeing the notification prompt, resulting in potential user confusion or spoofing attacks. References

CVE-2022-45405: Use-after-free in InputStream implementation

Reporter

Samuel Groß

Impact

high

Description

If an out-of-memory condition occurred when creating a JavaScript global, a JavaScript realm may be deleted while references to it lived on in a BaseShape. This could lead to a use-after-free causing a potentially exploitable crash. References

Bug 1791975

CVE-2022-45408: Fullscreen notification bypass via windowName

Reporter

Irvan Kurniawan

Impact

high

Description

Through a series of popups that reuse windowName, an attacker can cause a window to go fullscreen without the user seeing the notification prompt, resulting in potential user confusion or spoofing attacks. References

CVE-2022-45409: Use-after-free in Garbage Collection

Reporter

Gary Kwong

Description

The garbage collector could have been aborted in several states and zones and GCRuntime::finishCollection may not have been called, leading to a use-after-free and potentially exploitable crash References

Bug 1796901

CVE-2022-45410: ServiceWorker-intercepted requests bypassed SameSite cookie policy

Reporter

Dongsung Kim

Impact

moderate

Description

When a ServiceWorker intercepted a request with FetchEvent, the origin of the request was lost after the ServiceWorker took ownership of it. This had the effect of negating SameSite cookie protections. This was addressed in the spec and then in browsers. References

Bug 1658869

CVE-2022-45411: Cross-Site Tracing was possible via non-standard override headers

Reporter

scarlet

Impact

moderate

Description

Cross-Site Tracing occurs when a server will echo a request back via the Trace method, allowing an XSS attack to access to authorization headers and cookies inaccessible to JavaScript (such as cookies protected by HTTPOnly). To mitigate this attack, browsers placed limits on fetch() and XMLHttpRequest; however some webservers have implemented non-standard headers such as X-Http-Method-Override that override the HTTP method, and made this attack possible again. Firefox has applied the same mitigations to the use of this and similar headers. References

Bug 1790311

CVE-2022-45412: Symlinks may resolve to partially uninitialized buffers

Reporter

Armin Ebert

Impact

moderate

Description

When resolving a symlink such as file:///proc/self/fd/1, an error message may be produced where the symlink was resolved to a string containing unitialized memory in the buffer. This bug only affects Firefox on Unix-based operated systems (Android, Linux, MacOS). Windows is unaffected. References

Bug 1791029CVE-2022-45416: Keystroke Side-Channel Leakage

Reporter

Erik Kraft, Martin Schwarzl, and Andrew McCreight

Impact

moderate

Description

Keyboard events reference strings like "KeyA" that were at fixed, known, and widely-spread addresses. Cache-based timing attacks such as Prime+Probe could have possibly figured out which keys were being pressed. References

Reporter

Hafiizh

Impact

moderate

Description

Bug 1792643

CVE-2022-45421: Memory safety bugs fixed in Firefox 107 and Firefox ESR 102.5

Reporter

Mozilla developers

Impact

high

Description

Mozilla developers Andrew McCreight and Gabriele Svelto reported memory safety bugs present in Firefox 106 and Firefox ESR 102.4. 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. References
