CVEs 4

In general, these flaws cannot be exploited through email in the Thunderbird product because scripting is disabled when reading mail, but are potentially risks in browser or browser-like contexts.

CVE-2022-42927: Same-origin policy violation could have leaked cross-origin URLs (high)
A same-origin policy violation could have allowed the theft of cross-origin URL entries, leaking the result of a redirect, via <code>performance.getEntries()</code>.
CVE-2022-42928: Memory Corruption in JS Engine (high)
Certain types of allocations were missing annotations that, if the Garbage Collector was in a specific state, could have lead to memory corruption and a potentially exploitable crash.
CVE-2022-42929: Denial of Service via window.print (moderate)
If a website called <code>window.print()</code> in a particular way, it could cause a denial of service of the browser, which may persist beyond browser restart depending on the user's session restore settings.
CVE-2022-42932: Memory safety bugs fixed in Thunderbird 102.4 (moderate)
Mozilla developers Ashley Hale and the Mozilla Fuzzing Team reported memory safety bugs present in Thunderbird 102.3. 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.
