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 •
CVSS: 2.5EPSS: 0%CPEs: 1EXPL: 1CVE-2021-29948 – Mozilla: Race condition when reading from disk while verifying signatures
https://notcve.org/view.php?id=CVE-2021-29948
Signatures are written to disk before and read during verification, which might be subject to a race condition when a malicious local process or user is replacing the file. This vulnerability affects Thunderbird < 78.10. Las firmas son escritas en el disco antes y se leen durante la verificación, lo que podría estar sujeto a una condición de carrera cuando un proceso local malicioso o un usuario está reemplazando el archivo.
