Executive Summary

This vulnerability is a heap over-read issue in the ea header parsing component of Netatalk versions 2.1.0 through 4.4.2. A heap over-read occurs when a program reads more data than it should from a heap-allocated memory area, potentially leading to information disclosure or program instability. This specific issue was fixed in version 4.5.0 of Netatalk.

Impact Analysis

The vulnerability has a CVSS base score of 4.2, indicating a low to medium severity. It can be exploited remotely (AV:N) but requires high attack complexity (AC:H) and low privileges (PR:L). There is no user interaction needed (UI:N). The impact is limited to low confidentiality loss (C:L) and low availability loss (A:L), with no impact on integrity (I:N). Therefore, an attacker could potentially read some sensitive information from memory and cause minor availability issues, but cannot modify data or fully disrupt the system.

Mitigation Strategies

To mitigate this vulnerability, upgrade Netatalk to version 4.5.0 or later, as the issue is fixed starting from that version.
