Descriptions

The SSL 3 HMAC functionality in wolfSSL CyaSSL 2.5.0 before 2.9.4 does not check the padding length when verification fails, which allows remote attackers to have unspecified impact via a crafted HMAC, which triggers an out-of-bounds read.

La funcionalidad SSL 3 HMAC en wolfSSL CyaSSL versiones 2.5.0 anteriores a 2.9.4, no comprueba la longitud del relleno cuando se presenta un fallo de verificación, lo que permite a atacantes remotos tener un impacto no especificado por medio de un HMAC diseñado, lo que desencadena una lectura fuera de límites.

Multiple vulnerabilities have been found in CyaSSL, the worst of which may allow attackers to execute arbitrary code. Versions 2.9.4 are affected.
