CVSS: 6.5EPSS: 0%CPEs: 4EXPL: 0CVE-2021-29951 – Mozilla Windows Maintenance Service Weak DACL
https://notcve.org/view.php?id=CVE-2021-29951
The Mozilla Maintenance Service granted SERVICE_START access to BUILTIN|Users which, in a domain network, grants normal remote users access to start or stop the service. This could be used to prevent the browser update service from operating (if an attacker spammed the 'Stop' command); but also exposed attack surface in the maintenance service. *Note: This issue only affected Windows operating systems older than Win 10 build 1709. Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 78.10.1, Firefox < 87, and Firefox ESR < 78.10.1. • https://bugzilla.mozilla.org/show_bug.cgi?id=1690062 https://www.mozilla.org/security/advisories/mfsa2021-10 https://www.mozilla.org/security/advisories/mfsa2021-18 https://www.mozilla.org/security/advisories/mfsa2021-19 • CWE-269: Improper Privilege Management •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 1CVE-2021-29950 – Mozilla: Logic issue potentially leaves key material unlocked
https://notcve.org/view.php?id=CVE-2021-29950
Thunderbird unprotects a secret OpenPGP key prior to using it for a decryption, signing or key import task. If the task runs into a failure, the secret key may remain in memory in its unprotected state. This vulnerability affects Thunderbird < 78.8.1. Thunderbird desprotege una clave secreta OpenPGP antes de usarla para una tarea de descifrado, firma o importación de claves. Si la tarea ejecuta un fallo, la clave secreta puede permanecer en la memoria en su estado desprotegido. • https://bugzilla.mozilla.org/show_bug.cgi?id=1673239 https://www.mozilla.org/security/advisories/mfsa2021-17 https://access.redhat.com/security/cve/CVE-2021-29950 https://bugzilla.redhat.com/show_bug.cgi?id=1951873 • CWE-312: Cleartext Storage of Sensitive Information CWE-522: Insufficiently Protected Credentials •
CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2021-29949 – Mozilla: Thunderbird might execute an alternative OTR library
https://notcve.org/view.php?id=CVE-2021-29949
When loading the shared library that provides the OTR protocol implementation, Thunderbird will initially attempt to open it using a filename that isn't distributed by Thunderbird. If a computer has already been infected with a malicious library of the alternative filename, and the malicious library has been copied to a directory that is contained in the search path for executable libraries, then Thunderbird will load the incorrect library. This vulnerability affects Thunderbird < 78.9.1. Cuando se carga la biblioteca compartida que proporciona la implementación del protocolo OTR, Thunderbird intentará inicialmente abrirla usando un nombre de archivo que no es distribuido por Thunderbird. Si un ordenador ya ha sido infectado con una biblioteca maliciosa con el nombre de archivo alternativo, y la biblioteca maliciosa ha sido copiada a un directorio que está contenido en la ruta de búsqueda de bibliotecas ejecutables, entonces Thunderbird cargará la biblioteca incorrecta. • https://bugzilla.mozilla.org/show_bug.cgi?id=1682101 https://www.mozilla.org/security/advisories/mfsa2021-13 https://access.redhat.com/security/cve/CVE-2021-29949 https://bugzilla.redhat.com/show_bug.cgi?id=1951872 • CWE-426: Untrusted Search Path CWE-427: Uncontrolled Search Path Element •
CVSS: 6.5EPSS: 0%CPEs: 3EXPL: 0CVE-2021-29945 – Mozilla: Incorrect size computation in WebAssembly JIT could lead to null-reads
https://notcve.org/view.php?id=CVE-2021-29945
The WebAssembly JIT could miscalculate the size of a return type, which could lead to a null read and result in a crash. *Note: This issue only affected x86-32 platforms. Other platforms are unaffected.*. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88. El JIT de WebAssembly podía calcular mal el tamaño de un tipo de retorno, lo que podía conllevar a una lectura nula y resultar en un bloqueo. • https://bugzilla.mozilla.org/show_bug.cgi?id=1700690 https://www.mozilla.org/security/advisories/mfsa2021-14 https://www.mozilla.org/security/advisories/mfsa2021-15 https://www.mozilla.org/security/advisories/mfsa2021-16 https://access.redhat.com/security/cve/CVE-2021-29945 https://bugzilla.redhat.com/show_bug.cgi?id=1951370 • CWE-476: NULL Pointer Dereference CWE-682: Incorrect Calculation •
CVSS: 8.8EPSS: 0%CPEs: 3EXPL: 0CVE-2021-29946 – Mozilla: Port blocking could be bypassed
https://notcve.org/view.php?id=CVE-2021-29946
Ports that were written as an integer overflow above the bounds of a 16-bit integer could have bypassed port blocking restrictions when used in the Alt-Svc header. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88. Los puertos que se escribieron como un desbordamiento de enteros por encima de los límites de un entero de 16 bits podrían haber omitido las restricciones de bloqueo de puertos cuando se usaron en la cabecera Alt-Svc. Esta vulnerabilidad afecta a Firefox ESR versiones anteriores a 78.10, Thunderbird versiones anteriores a 78.10 y Firefox versiones anteriores a 88 • https://bugzilla.mozilla.org/show_bug.cgi?id=1698503 https://www.mozilla.org/security/advisories/mfsa2021-14 https://www.mozilla.org/security/advisories/mfsa2021-15 https://www.mozilla.org/security/advisories/mfsa2021-16 https://access.redhat.com/security/cve/CVE-2021-29946 https://bugzilla.redhat.com/show_bug.cgi?id=1951371 • CWE-190: Integer Overflow or Wraparound •
