CVE-2026-44048 Details
Description
A stack-based buffer overflow via UCS-2 type confusion in convert_charset() in Netatalk 2.0.4 through 4.4.2 allows a remote authenticated attacker to execute arbitrary code or cause a denial of service.
A stack buffer overflow vulnerability has been identified in Netatalk versions 2.0.4 through 4.4.2. This issue arises from a type confusion related to UCS-2 encoding in the 'convert_charset()' function, allowing for potential memory corruption. An authenticated client could exploit this vulnerability, possibly leading to a process crash or more extensive memory corruption.
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.
