Descriptions

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

Un desbordamiento de entero en la función process_bin_update en Memcached, que es responsable de procesar múltiples comandos de protocolo 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 the memcached binary protocol. An attacker could create a specially crafted message that would cause the memcached server to crash or, potentially, execute arbitrary code.
