CVE-2026-44056 Details
Description
A stack-based buffer overflow in desktop.c in Netatalk 1.3 through 4.2.2 allows a remote authenticated attacker to cause a denial of service, obtain limited information, or modify limited data.
A stack buffer overflow vulnerability has been identified in Netatalk versions 1.3 through 4.2.2. The issue arises in the 'desktop.c' file, where the application improperly handles long directory entry names, allowing them to overflow a small stack buffer. This vulnerability could lead to a denial-of-service condition. The practical impact may vary depending on whether an authenticated user can manipulate the affected metadata to trigger ownership or mode updates.
Users can upgrade to Netatalk version 4.5.0 or later, which includes the necessary patch. Alternatively, the patch can be applied to a Netatalk 4.4.2 source tree to hotfix the vulnerability.
