Descriptions
sql/password.c in Oracle MySQL 5.1.x before 5.1.63, 5.5.x before 5.5.24, and 5.6.x before 5.6.6, and MariaDB 5.1.x before 5.1.62, 5.2.x before 5.2.12, 5.3.x before 5.3.6, and 5.5.x before 5.5.23, when running in certain environments with certain implementations of the memcmp function, allows remote attackers to bypass authentication by repeatedly authenticating with the same incorrect password, which eventually causes a token comparison to succeed due to an improperly-checked return value.
sql/password.c en Oracle MySQL 5.1.x anterior a 5.1.63, 5.5.x anterior a 5.5.24, y 5.6.x anterior a 5.6.6, y MariaDB 5.1.x anterior a 5.1.62, 5.2.x anterior a 5.2.12, 5.3.x anterior a 5.3.6, y 5.5.x anterior a 5.5.23, cuando se ejecuta en determinados entornos con determinadas implementaciones de la función memcmp, permite que atacantes remotos eviten la autenticación utilizando repetidamente la misma contraseña incorrecta, lo que eventualmente provoca una comparación de token con resultado de éxito en una variable de retorno no validada
Multiple vulnerabilities have been found in MySQL, allowing attackers to execute arbitrary code or cause Denial of Service. Versions less than 5.1.70 are affected.
