CyberRota Analysis

AI-Generated

A vulnerability exists in the ISO Presentation layer due to improper handling of parameters during normal mode negotiation, allowing an attacker to exploit a missing length check. This can lead to a bounded heap over-read, causing the affected process to terminate and resulting in a denial of service. Organizations utilizing systems that rely on the ISO Presentation layer should prioritize addressing this issue to mitigate potential service disruptions.

Original NVD Description

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.
