Memory safety bug present in Firefox 124, Firefox ESR 115.9, and
Thunderbird 115.9. This bug showed evidence of memory corruption and we
presume that with enough effort this could have been exploited to run
arbitrary code. This vulnerability affects Firefox < 125, Firefox ESR <
115.10, and Thunderbird < 115.10.
