#CVE-2022-45403: Service Workers might have learned size of cross-origin media files
ReporterAnne van Kesteren and Karl TomlinsonImpacthigh
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.
#CVE-2022-45404: Fullscreen notification bypass
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.
#CVE-2022-45405: Use-after-free in InputStream implementation
nsIInputStream‘s on a different thread than creation could have led to a use-after-free and potentially exploitable crash.
#CVE-2022-45408: Fullscreen notification bypass via windowName
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.
#CVE-2022-45409: Use-after-free in Garbage Collection
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
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.
#CVE-2022-45411: Cross-Site Tracing was possible via non-standard override headers
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. Thunderbird has applied the same mitigations to the use of this and similar headers.
#CVE-2022-45412: Symlinks may resolve to partially uninitialized buffers
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 Thunderbird on Unix-based operated systems (Android, Linux, MacOS). Windows is unaffected.
#CVE-2022-45416: Keystroke Side-Channel Leakage
ReporterErik Kraft, Martin Schwarzl, and Andrew McCreightImpactmoderate
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.
#CVE-2022-45418: Custom mouse cursor could have been drawn over browser UI
If a custom mouse cursor is specified in CSS, under certain circumstances the cursor could have been drawn over the browser UI, resulting in potential user confusion or spoofing attacks.
#CVE-2022-45420: Iframe contents could be rendered outside the iframe
ReporterSuhwan Song of SNU CompSec LabImpactlow
Use tables inside of an iframe, an attacker could have caused iframe contents to be rendered outside the boundaries of the iframe, resulting in potential user confusion or spoofing attacks.
#CVE-2022-45421: Memory safety bugs fixed in Thunderbird 102.5
Mozilla developers Andrew McCreight and Gabriele Svelto reported memory safety bugs present in Thunderbird 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.
