If a user were\ntricked into opening a specially crafted website, an attacker could\npotentially exploit these to cause a denial of service, obtain sensitive\ninformation across domains, or execute arbitrary code. (CVE-2024-3852,\nCVE-2024-3864, CVE-2024-3865)\n\nBartek Nowotarski discovered that Firefox did not properly limit HTTP/2\nCONTINUATION frames. An attacker could potentially exploit this issue to\ncause a denial of service. (CVE-2024-3302)\n\nGary Kwong discovered that Firefox did not properly manage memory when\nrunning garbage collection during realm initialization. An attacker could\npotentially exploit this issue to cause a denial of service, or execute\narbitrary code. (CVE-2024-3853)\n\nLukas Bernhard discovered that Firefox did not properly manage memory\nduring JIT optimisations, leading to an out-of-bounds read vulnerability.\nAn attacker could possibly use this issue to cause a denial of service or\nexpose sensitive information. (CVE-2024-3854, CVE-2024-3855)\n\nNan Wang discovered that Firefox did not properly manage memory during\nWASM garbage collection. An attacker could potentially exploit this issue\nto cause a denial of service, or execute arbitrary code.
