Feiten
Mozilla heeft kwetsbaarheden verholpen in Firefox en Thunderbird (Specifiek voor versies onder 135 en 128.7).
Interpretaties
De kwetsbaarheden omvatten onder andere een double-free kwetsbaarheid, use-after-free condities, en race conditions die kunnen leiden tot geheugenbeschadiging, ongeautoriseerde toegang, en privacyrisico's. Kwaadwillenden kunnen deze kwetsbaarheden misbruiken om willekeurige code uit te voeren, spoofing-aanvallen uit te voeren, en gevoelige gebruikersdata bloot te stellen.
Voor succesvol misbruik moet de kwaadwillende het slachtoffer misleiden een malafide pagina te openen of link te volgen.
Oplossingen
Mozilla heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.

Summary
Memory safety bugs present in Firefox 134, Thunderbird 134, Firefox ESR 128.6, and Thunderbird 128.6. 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. This vulnerability affects Firefox < 135, Firefox ESR < 128.7, Thunderbird < 128.7, and Thunderbird < 135.

Summary
The Thunderbird Address Book URI fields contained unsanitized links. This could be used by an attacker to create and export an address book containing a malicious payload in a field. For example, in the “Other” field of the Instant Messaging section. If another user imported the address book, clicking on the link could result in opening a web page inside Thunderbird, and that page could execute (unprivileged) JavaScript. This vulnerability affects Thunderbird < 128.7 and Thunderbird < 135.

Summary
Memory safety bugs present in Firefox 134, Thunderbird 134, Firefox ESR 115.19, Firefox ESR 128.6, Thunderbird 115.19, and Thunderbird 128.6. 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. This vulnerability affects Firefox < 135, Firefox ESR < 115.20, Firefox ESR < 128.7, Thunderbird < 128.7, and Thunderbird < 135.
Severity ?
