Compliance Impact

This vulnerability allows a remote authenticated attacker to obtain sensitive information, which could potentially lead to non-compliance with data protection regulations such as GDPR and HIPAA that require the protection of sensitive data.

Additionally, the minor service disruption caused by the vulnerability might impact availability requirements under these standards.

Executive Summary

This vulnerability exists in Netatalk versions 3.1.0 through 4.4.2 and involves heap out-of-bounds reads during spotlight RPC unmarshalling. This means that when processing certain remote procedure calls related to spotlight functionality, the software reads memory outside the allocated heap buffer, which can lead to unexpected behavior or crashes. The issue was fixed in version 4.4.3.

Impact Analysis

The vulnerability has a CVSS v3.1 base score of 7.1, indicating a high severity. It can be exploited remotely with low attack complexity and requires low privileges but no user interaction. The impact includes high confidentiality impact, no integrity impact, and low availability impact. This means an attacker could potentially read sensitive information from memory, but cannot modify data or significantly disrupt service.
