Summary
Arjun Basnet discovered that Netatalk improperly validated inputs when
unmarshalling Spotlight Remote Procedure Call. A remote authenticated
attacker could possibly use this issue to cause a denial of service or
obtain sensitive information. (CVE-2026-44066)
Arjun Basnet discovered that Netatalk improperly sanitized extended
attribute path components. A remote authenticated attacker could possibly
use this issue to perform path traversal attacks and write to arbitrary
files outside the intended metadata directory. (CVE-2026-44068)

Vulnerabilities 2
-
High 7.6
EA path traversal via incomplete sanitization
Incomplete sanitization of extended attribute (EA) path components in Netatalk 2.1.0 through 4.4.2 allows a remote authenticated attacker to write to files outside the intended metadata namespace via crafted EA names.
-
High 7.1
Heap out-of-bounds reads in Spotlight RPC unmarshalling
Multiple heap out-of-bounds reads in the Spotlight RPC unmarshalling code in Netatalk 3.1.0 through 4.4.2 allow a remote authenticated attacker to obtain sensitive information or cause a minor service disruption.
