Descripción

*** Pendiente de traducción *** The MMS server connection handler contains a flaw in its processing of <br /> BER-encoded request data. When an MMS confirmed request PDU containing <br /> an extended BER tag is received over an established session, the decoder<br /> may advance its internal buffer incorrectly due to a missing bounds <br /> check. This results in a one byte heap out-of-bounds read and causes the<br /> MMS service process to terminate, leading to a denial-of-service <br /> condition.
