CVE-2024-3864

Error de seguridad de la memoria presente en Firefox 124, Firefox ESR 115.9 y Thunderbird 115.9. Este error mostró evidencia de corrupción de memoria y suponemos que con suficiente esfuerzo esto podría haberse aprovechado para ejecutar código arbitrario. Esta vulnerabilidad afecta a Firefox < 125 y Firefox ESR < 115.10.

The Mozilla Foundation Security Advisory describes this flaw as: Memory safety bug present in Firefox 124, Firefox ESR 115.9, and Thunderbird 115.9. This bug showed evidence of memory corruption and we presume that with enough effort this could have been exploited to run arbitrary code.

USN-6747-1 fixed vulnerabilities in Firefox. The update introduced several minor regressions. This update fixes the problem. Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information across domains, or execute arbitrary code. Bartek Nowotarski discovered that Firefox did not properly limit HTTP/2 CONTINUATION frames. An attacker could potentially exploit this issue to cause a denial of service. Gary Kwong discovered that Firefox did not properly manage memory when running garbage collection during realm initialization. An attacker could potentially exploit this issue to cause a denial of service, or execute arbitrary code. Lukas Bernhard discovered that Firefox did not properly manage memory during JIT optimizations, leading to an out-of-bounds read vulnerability. An attacker could possibly use this issue to cause a denial of service or expose sensitive information. Nan Wang discovered that Firefox did not properly manage memory during WASM garbage collection. An attacker could potentially exploit this issue to cause a denial of service, or execute arbitrary code. Various other issues were also addressed.
