Mozilla -- multiple vulnerabilities

· CVE-2026-0892, CVE-2026-0889, CVE-2026-0888, CVE-2026-0881 · VuXML entry

Memory safety bugs present in Firefox 146 and Thunderbird 146. 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. Denial-of-service in the DOM: Service Workers component. Information disclosure in the XML component. Sandbox escape in the Messaging System component.

Affected versions

By system

2 still vulnerable, 2 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.
