Feiten
Zoom heeft kwetsbaarheden verholpen in Zoom Clients (Specifiek voor versies voor Linux, Windows, iOS en macOS).
Interpretaties
De kwetsbaarheden omvatten onjuiste certificaatvalidatie in Zoom Workplace voor Linux, een buffer overflow in specifieke Zoom Clients voor Windows, cross-site scripting in Zoom Clients voor Windows, onvoldoende controle over de stroom in Zoom Clients voor iOS, en onjuiste authenticatie in Zoom Clients voor macOS. Deze kwetsbaarheden kunnen door ongeautoriseerde gebruikers worden misbruikt om toegang te krijgen tot gevoelige informatie of om een Denial-of-Service-aanval uit te voeren. Dit kan leiden tot ongeautoriseerde informatie openbaarmaking en verstoring van diensten voor gebruikers en organisaties die afhankelijk zijn van het Zoom-platform.
Oplossingen
Zoom heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
