https://notcve.org/view.php?id=CVE-2013-1895

The py-bcrypt module before 0.3 for Python does not properly handle concurrent memory access, which allows attackers to bypass authentication via multiple authentication requests, which trigger the password hash to be overwritten. El módulo py-bcrypt versiones anteriores a 0.3 para Python, no maneja apropiadamente el acceso concurrente a la memoria, que permite a atacantes omitir la autenticación por medio de múltiples peticiones de autenticación, lo que desencadena que el hash de contraseña se sobrescriba. • http://lists.fedoraproject.org/pipermail/package-announce/2013-April/101382.html http://lists.fedoraproject.org/pipermail/package-announce/2013-April/101387.html http://www.openwall.com/lists/oss-security/2013/03/26/2 http://www.securityfocus.com/bid/58702 https://exchange.xforce.ibmcloud.com/vulnerabilities/83039 • CWE-307: Improper Restriction of Excessive Authentication Attempts •
