Descriptions
Integer overflow in the EVP_EncryptUpdate function in crypto/evp/evp_enc.c in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h allows remote attackers to cause a denial of service (heap memory corruption) via a large amount of data.
Desbordamiento de entero en la función EVP_EncryptUpdate en crypto/evp/evp_enc.c en OpenSSL en versiones anteriores a 1.0.1t y 1.0.2 en versiones anteriores a 1.0.2h permite a atacantes remotos provocar una denegación de servicio (corrupción de memoria dinámica) a través de una gran cantidad de datos.
An integer overflow flaw, leading to a buffer overflow, was found in the way the EVP_EncryptUpdate() function of OpenSSL parsed very large amounts of input data. A remote attacker could use this flaw to crash an application using OpenSSL or, possibly, execute arbitrary code with the permissions of the user running that application.
