ARM mbedTLS version 2.7.0 and earlier contains a Ciphersuite Allows Incorrectly Signed Certificates vulnerability in mbedtls_ssl_get_verify_result() that can result in ECDSA-signed certificates are accepted, when only RSA-signed ones should be.. This attack appear to be exploitable via Peers negotiate a TLS-ECDH-RSA-* ciphersuite. Any of the peers can then provide an ECDSA-signed certificate, when only an RSA-signed one should be accepted.. ARM mbedTLS, en versiones 2.7.0 y anteriores, contiene una vulnerabilidad de conjunto de cifrado que permite certificados firmados de forma incorrecta en mbedtls_ssl_get_verify_result(). Esto puede resultar en que se acepten certificados firmados por ECDSA, aunque solo deberían aceptarse los firmados por RSA. • https://github.com/ARMmbed/mbedtls/issues/1561 • CWE-295: Improper Certificate Validation •

ARM mbed TLS before 2.1.11, before 2.7.2, and before 2.8.0 has a buffer over-read in ssl_parse_server_psk_hint() that could cause a crash on invalid input. ARM mbed TLS, en versiones anteriores a la 2.1.11, anteriores a la 2.7.2 y anteriores a la 2.8.0, tiene una sobrelectura de búfer en ssl_parse_server_psk_hint() que podría provocar un cierre inesperado o una entrada no válida. • https://github.com/ARMmbed/mbedtls/commit/5224a7544c95552553e2e6be0b4a789956a6464e https://github.com/ARMmbed/mbedtls/commit/740b218386083dc708ce98ccc94a63a95cd5629e https://lists.debian.org/debian-lts-announce/2018/09/msg00029.html https://lists.debian.org/debian-lts-announce/2021/11/msg00021.html https://tls.mbed.org/tech-updates/releases/mbedtls-2.8.0-2.7.2-and-2.1.11-released • CWE-125: Out-of-bounds Read •

In ARM mbed TLS before 2.7.0, there is a bounds-check bypass through an integer overflow in PSK identity parsing in the ssl_parse_client_psk_identity() function in library/ssl_srv.c. En ARM mbed TLS, en versiones anteriores a la 2.7.0, hay una omisión de comprobación de límites mediante un desbordamiento de enteros en el análisis de identidad PSK en la función ssl_parse_client_psk_identity() en library/ssl_srv.c. • http://www.securityfocus.com/bid/103055 https://github.com/ARMmbed/mbedtls/blob/master/ChangeLog https://github.com/ARMmbed/mbedtls/commit/83c9f495ffe70c7dd280b41fdfd4881485a3bc28 https://security.gentoo.org/glsa/201804-19 https://usn.ubuntu.com/4267-1 https://www.debian.org/security/2018/dsa-4138 https://www.debian.org/security/2018/dsa-4147 • CWE-190: Integer Overflow or Wraparound •

ARM mbed TLS before 1.3.22, before 2.1.10, and before 2.7.0 allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow) via a crafted certificate chain that is mishandled during RSASSA-PSS signature verification within a TLS or DTLS session. ARM mbed TLS, en versiones anteriores a la 1.3.22, a la 2.1.10 y a la 2.7.0, permite que atacantes remotos ejecuten código arbitrario o provoquen una denegación de servicio (desbordamiento de búfer) mediante una cadena de certificados manipulada que se gestiona de manera incorrecta durante la verificación de firmas RSASSA-PSS en una sesión TLS o DTLS. • http://www.securityfocus.com/bid/103056 https://security.gentoo.org/glsa/201804-19 https://tls.mbed.org/tech-updates/security-advisories/mbedtls-security-advisory-2018-01 https://usn.ubuntu.com/4267-1 https://www.debian.org/security/2018/dsa-4138 https://www.debian.org/security/2018/dsa-4147 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
