Executive Summary

This vulnerability is caused by insufficient input validation in NetScaler ADC and NetScaler Gateway products. Specifically, when the TCP TimeStamp feature is enabled in the TCP Profile and associated with a virtual server (such as Load Balancing, Content Switching, or VPN types) or a configured service, it can lead to a memory overread condition.

Impact Analysis

The impact of this vulnerability is a memory overread, which means that the system may read memory beyond the intended buffer. This can potentially lead to information disclosure or system instability, depending on how the overread memory is handled.
