Descripción

*** Pendiente de traducción *** The ISO Presentation layer contains a flaw in the handling of specific <br /> parameters during normal mode negotiation. A missing length check in the<br /> processing of the encoded presentation data allows an attacker <br /> controlled field with a zero length value to trigger a bounded heap over<br /> read. This condition occurs before MMS session establishment, a crafted<br /> TCP/102 connection attempt can trigger the issue. The resulting over <br /> read causes the process to terminate, leading to a denial of service <br /> condition.
