VCID-1xcg-n9k4-tqc4 A bug in WebAssembly code generation could have lead to a crash. It may have been possible for an attacker to leverage this to achieve code execution. CVE-2025-1011
VCID-95g4-dcau-6bd1 The z-order of the browser windows could be manipulated to hide the fullscreen notification. This could potentially be leveraged to perform a spoofing attack. CVE-2025-1019
VCID-bzgb-mdsk-yua6 An attacker could have caused a use-after-free via crafted XSLT data, leading to a potentially exploitable crash. CVE-2025-1009
VCID-cypj-1jsu-cbh5 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. CVE-2025-1016
VCID-f5w8-j656-akf4 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. CVE-2025-1017

VCID-ms9h-982a-pkdu Certificate length was not properly checked when added to a certificate store. In practice only trusted data was processed. CVE-2025-1014
VCID-n529-v6zj-n3gf The fullscreen notification is prematurely hidden when fullscreen is re-requested quickly by the user. This could have been leveraged to perform a potential spoofing attack. CVE-2025-1018
VCID-pj4h-ff45-e3ez A race condition could have led to private browsing tabs being opened in normal browsing windows. This could have resulted in a potential privacy leak. CVE-2025-1013
VCID-prve-an93-pkd8 Memory safety bugs present in Firefox 134 and Thunderbird 134. 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. CVE-2025-1020
VCID-ymu8-mjph-f7a4 A race during concurrent delazification could have led to a use-after-free. CVE-2025-1012
