https://notcve.org/view.php?id=CVE-2021-43666
A Denial of Service vulnerability exists in mbed TLS 3.0.0 and earlier in the mbedtls_pkcs12_derivation function when an input password's length is 0. Se presenta una vulnerabilidad de denegación de servicio en mbed TLS 3.0.0 y anteriores, en la función mbedtls_pkcs12_derivation cuando la longitud de una contraseña de entrada es 0 • https://github.com/ARMmbed/mbedtls/issues/5136 https://lists.debian.org/debian-lts-announce/2022/12/msg00036.html •
CVE-2021-45450
https://notcve.org/view.php?id=CVE-2021-45450
In Mbed TLS before 2.28.0 and 3.x before 3.1.0, psa_cipher_generate_iv and psa_cipher_encrypt allow policy bypass or oracle-based decryption when the output buffer is at memory locations accessible to an untrusted application. En Mbed TLS versiones anteriores a 2.28.0 y 3.x versiones anteriores a 3.1.0, las funciones psa_cipher_generate_iv y psa_cipher_encrypt permiten omitir la política o el descifrado basado en oráculos cuando el búfer de salida es encontrado en ubicaciones de memoria accesibles para una aplicación no confiable • https://github.com/ARMmbed/mbedtls/releases/tag/v2.28.0 https://github.com/ARMmbed/mbedtls/releases/tag/v3.1.0 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/IL66WKJGXY5AXMTFE7QDMGL3RIBD6PX5 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TALJHOYAYSUJTLN6BYGLO4YJGNZUY74W https://security.gentoo.org/glsa/202301-08 • CWE-327: Use of a Broken or Risky Cryptographic Algorithm •

CVE-2021-44732
https://notcve.org/view.php?id=CVE-2021-44732
Mbed TLS before 3.0.1 has a double free in certain out-of-memory conditions, as demonstrated by an mbedtls_ssl_set_session() failure. Mbed TLS versiones anteriores a 3.0.1,presenta una doble liberación en determinadas condiciones de salida de memoria, como es demostrado por un fallo de la función mbedtls_ssl_set_session() • https://bugs.gentoo.org/829660 https://github.com/ARMmbed/mbedtls/releases https://github.com/ARMmbed/mbedtls/releases/tag/v2.16.12 https://github.com/ARMmbed/mbedtls/releases/tag/v2.28.0 https://github.com/ARMmbed/mbedtls/releases/tag/v3.1.0 https://lists.debian.org/debian-lts-announce/2022/12/msg00036.html https://tls.mbed.org/tech-updates/security-advisories/mbedtls-security-advisory-2021-12 • CWE-415: Double Free •
CVE-2020-36475
https://notcve.org/view.php?id=CVE-2020-36475
An issue was discovered in Mbed TLS before 2.25.0 (and before 2.16.9 LTS and before 2.7.18 LTS). The calculations performed by mbedtls_mpi_exp_mod are not limited; thus, supplying overly large parameters could lead to denial of service when generating Diffie-Hellman key pairs. Se ha detectado un problema en Mbed TLS versiones anteriores a 2.25.0 (y versiones anteriores a 2.16.9 LTS y versiones anteriores a 2.7.18 LTS). Los cálculos llevado a cabo por la función mbedtls_mpi_exp_mod no están limitados; por lo tanto, el suministro de parámetros demasiado grandes podría conllevar a una denegación de servicio cuando se generan pares de claves Diffie-Hellman. • https://cert-portal.siemens.com/productcert/pdf/ssa-756638.pdf https://github.com/ARMmbed/mbedtls/releases/tag/v2.16.9 https://github.com/ARMmbed/mbedtls/releases/tag/v2.25.0 https://github.com/ARMmbed/mbedtls/releases/tag/v2.7.18 https://lists.debian.org/debian-lts-announce/2021/11/msg00021.html https://lists.debian.org/debian-lts-announce/2022/12/msg00036.html • CWE-131: Incorrect Calculation of Buffer Size •
