Descripción

*** Pendiente de traducción *** The MMS BER decoder contains a boundary-handling flaw in the processing <br /> of certain fields within confirmed-request messages. When a crafted <br /> BER-encoded element is received over an established MMS session (TCP <br /> port 102), the decoder may advance its internal read position <br /> incorrectly, leading to a heap out-of-bounds read. This condition causes<br /> the MMS handling process to terminate unexpectedly, resulting in a <br /> denial-of-service.
