Summary

Mozilla heeft kwetsbaarheden verholpen in Firefox en Thunderbird (Specifiek voor versies onder 134 en 128.6).

Interpretaties
De kwetsbaarheden omvatten onder andere client-side path traversal, privilege escalation en use-after-free condities. Deze kwetsbaarheden kunnen door kwaadwillenden worden misbruikt om ongeautoriseerde toegang te verkrijgen, crashes te veroorzaken of mogelijkerwijze willekeurige code uit te voeren.

Oplossingen
Mozilla heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
