What is CVE-2026-44071?

Netatalk versions 3.1.2 through 4.4.2 contain a vulnerability due to being compiled without FORTIFY_SOURCE, which disables crucial runtime checks for buffer overflows. This oversight could enable a remote attacker to exploit memory errors, leading to a minor denial of service. The absence of built-in protection means potential risks could escalate if the vulnerabilities are not addressed promptly.

Affected Version(s)

Netatalk 3.1.2 <= 4.4.2

Netatalk 4.5.0
