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