CVSS: 8.8EPSS: 0%CPEs: 6EXPL: 0CVE-2021-43539 – Mozilla: GC rooting failure when calling wasm instance methods
https://notcve.org/view.php?id=CVE-2021-43539
Failure to correctly record the location of live pointers across wasm instance calls resulted in a GC occurring within the call not tracing those live pointers. This could have led to a use-after-free causing a potentially exploitable crash. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and Firefox < 95. Un fallo en el registro correcto de la ubicación de los punteros vivos a través de las llamadas a instancias de wasm daba lugar a que una GC que ocurría dentro de la llamada no rastreara esos punteros vivos. Esto podría haber conllevado a un uso de memoria previamente liberada causando un bloqueo potencialmente explotable. • https://bugzilla.mozilla.org/show_bug.cgi?id=1739683 https://lists.debian.org/debian-lts-announce/2021/12/msg00030.html https://lists.debian.org/debian-lts-announce/2022/01/msg00001.html https://security.gentoo.org/glsa/202202-03 https://security.gentoo.org/glsa/202208-14 https://www.debian.org/security/2021/dsa-5026 https://www.debian.org/security/2022/dsa-5034 https://www.mozilla.org/security/advisories/mfsa2021-52 https://www.mozilla.org/security/advisories/mfsa2021-53 • CWE-416: Use After Free •

An incorrect type conversion of sizes from 64bit to 32bit integers allowed an attacker to corrupt memory leading to a potentially exploitable crash. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and Firefox < 95. Una conversión de tipo incorrecta de los tamaños de enteros de 64 bits a 32 bits permitía a un atacante corromper la memoria, conllevando a un bloqueo potencialmente explotable. Esta vulnerabilidad afecta a Thunderbird versiones anteriores a 91.4.0, Firefox ESR versiones anteriores a 91.4.0, y Firefox versiones anteriores a 95 The Mozilla Foundation Security Advisory describes this flaw as: An incorrect type conversion of sizes from 64bit to 32bit integers allowed an attacker to corrupt memory leading to a potentially exploitable crash. • https://bugzilla.mozilla.org/show_bug.cgi?id=1738237 https://lists.debian.org/debian-lts-announce/2021/12/msg00030.html https://lists.debian.org/debian-lts-announce/2022/01/msg00001.html https://security.gentoo.org/glsa/202202-03 https://security.gentoo.org/glsa/202208-14 https://www.debian.org/security/2021/dsa-5026 https://www.debian.org/security/2022/dsa-5034 https://www.mozilla.org/security/advisories/mfsa2021-52 https://www.mozilla.org/security/advisories/mfsa2021-53 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-704: Incorrect Type Conversion or Cast •

ModSecurity 3.x through 3.0.5 mishandles excessively nested JSON objects. Crafted JSON objects with nesting tens-of-thousands deep could result in the web server being unable to service legitimate requests. Even a moderately large (e.g., 300KB) HTTP request can occupy one of the limited NGINX worker processes for minutes and consume almost all of the available CPU on the machine. Modsecurity 2 is similarly vulnerable: the affected versions include 2.8.0 through 2.9.4. ModSecurity versiones 3.x hasta 3.0.5, maneja inapropiadamente los objetos JSON excesivamente anidados. • https://github.com/EkamSinghWalia/Detection-and-Mitigation-script-for-CVE-2021-42717 https://lists.debian.org/debian-lts-announce/2022/05/msg00042.html https://www.debian.org/security/2021/dsa-5023 https://www.oracle.com/security-alerts/cpuapr2022.html https://www.trustwave.com/en-us/resources/blogs/spiderlabs-blog/modsecurity-dos-vulnerability-in-json-parsing-cve-2021-42717 • CWE-674: Uncontrolled Recursion •
