[email protected] reports: An attacker was able to perform an out-of-bounds read or write on a JavaScript object by confusing array index sizes.
Affected versions

- firefox-esr < 128.10.1
By system
1 still vulnerable, 3 fixed. Where VuXML applies (FreeBSD, DragonFly, FreeBSD's derivatives) a port is vulnerable while its version is in a range; pkgsrc says itself whether it lists a CVE of this advisory; OpenBSD and MidnightBSD keep no list this site reads, so their row is only an estimate: FreeBSD's ranges applied to upstream's version.
