Executive Summary

This vulnerability affects IBM HTTP Server versions 8.5 and 9.0. It is a denial of service (DoS) vulnerability that occurs via the optional module mod_mem_cache.

Impact Analysis

The vulnerability can cause a denial of service condition, meaning that the affected IBM HTTP Server could become unavailable or unresponsive, impacting the availability of services relying on it.

Compliance Impact

The vulnerability in IBM HTTP Server 8.5 and 9.0 allows for a denial of service via the optional module mod_mem_cache. This impacts availability but does not affect confidentiality or integrity.

Since the vulnerability causes denial of service without compromising data confidentiality or integrity, its direct impact on compliance with standards like GDPR or HIPAA—which focus heavily on data protection and privacy—is limited.

However, availability is also a component of these regulations, so prolonged denial of service could potentially affect compliance related to system availability requirements.
