Versions prior to 0.5.3, 0.6.2, and 0.7.1 are vulnerable to out-of-bounds read. A specially crafted header of swtpm's state, where the blobheader's hdrsize indicator has an invalid value, may cause an out-of-bounds access when the byte array representing the state of the TPM is accessed. This will likely crash swtpm or prevent it from starting since the state cannot be understood. Users should upgrade to swtpm v0.5.3, v0.6.2, or v0.7.1 to receive a patch. There are currently no known workarounds."},{"lang":"es","value":"swtpm es un emulador de TPM basado en libtpms con socket, dispositivo de caracteres e interfaz Linux CUSE. Las versiones anteriores a 0.5.3, 0.6.2 y 0.7.1, son vulnerables a una lectura fuera de límites. Un encabezado especialmente diseñado del estado de swtpm, donde el indicador hdrsize del blobheader presenta un valor no válido, puede causar un acceso fuera de límites cuando es accedido al array de bytes que representa el estado del TPM. Esto probablemente bloqueará swtpm o impedirá que sea iniciado ya que el estado no puede ser entendido. Los usuarios deben actualizar a swtpm versión v0.5.3, v0.6.2, o v0.7.1 para recibir un parche.
