Descriptions

An integer overflow in process_bin_sasl_auth function in Memcached, which is responsible for authentication commands of Memcached binary protocol, can be abused to cause heap overflow and lead to remote code execution.

Desbordamiento de entero en la función process_bin_sasl_auth en Memcached, que es es responsable de autenticar los comandos del código binario Memcached, puede ser abusado para provocar desbordamiento en la memoria dinámica y conducir a la ejecución remota de código.

An integer overflow flaw, leading to a heap-based buffer overflow, was found in memcached's parsing of SASL authentication messages. An attacker could create a specially crafted message that would cause the memcached server to crash or, potentially, execute arbitrary code.
