CyberRota Analysis

AI-Generated

The vulnerability exists in the MMS BER decoder, which improperly handles boundary conditions in confirmed-request messages, potentially allowing a crafted BER-encoded element to cause a heap out-of-bounds read. This flaw can lead to an unexpected termination of the MMS handling process, resulting in a denial-of-service condition. Organizations utilizing MMS services over TCP port 102 should prioritize addressing this issue to mitigate potential service disruptions.

Original NVD Description

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