Announced: August 23, 2022
Impact: high
Products: Firefox
Fixed in: Firefox 104
# CVE-2022-38472: Address bar spoofing via XSLT error handling
Reporter: Armin Ebert
Impact: high
Description
An attacker could have abused XSLT error handling to associate
attacker-controlled content with another origin which was displayed in the
address bar. This could have been used to fool the user into submitting data
intended for the spoofed origin.

# CVE-2022-38473: Cross-origin XSLT Documents would have inherited the parent's
permissions
Reporter: Armin Ebert
Impact: high
Description
A cross-origin iframe referencing an XSLT document would inherit the parent
domain's permissions (such as microphone or camera access).

o Bug 1771685
# CVE-2022-38474: Recording notification not shown when microphone was recording
on Android
Reporter: Agi Sferro
Impact: low
Description
A website that had permission to access the microphone could record audio
without the audio notification being shown. This bug does not allow the
attacker to bypass the permission prompt - it only affects the notification
shown once permission has been granted.
This bug only affects Firefox for Android. Other operating systems are
unaffected.

# CVE-2022-38475: Attacker could write a value to a zero-length array
Reporter: Christian Holler
Impact: low
Description
An attacker could have written a value to the first element in a zero-length
JavaScript array. Although the array was zero-length, the value was not written
to an invalid memory address.

# CVE-2022-38477: Memory safety bugs fixed in Firefox 104 and Firefox ESR 102.2
Reporter: Mozilla developers and community
Impact: high
Description
Mozilla developer Nika Layzell and the Mozilla Fuzzing Team reported memory
safety bugs present in Firefox 103 and Firefox ESR 102.1. 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.
