CVE-2026-44062 Details
Description
A missing output length bounds check in pull_charset_flags() in Netatalk 2.0.4 through 4.4.2 allows a remote authenticated attacker to execute arbitrary code or cause a denial of service via crafted character set data.
A vulnerability exists in Netatalk versions 2.0.4 through 4.4.2, due to a missing bounds check in the 'pull_charset_flags()' function. This flaw allows for memory corruption by writing beyond the allocated output space while handling crafted filename or path data. An authenticated client could potentially exploit this issue, with the actual impact depending on triggering specific conversion states with unusually long filenames or paths.
Users can upgrade to Netatalk version 4.4.3 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.
