CVE-2026-44065 Details
Description
An off-by-two error in lp_write() in papd in Netatalk 2.0.0 through 4.4.2 allows an adjacent network attacker to modify limited data or cause a minor service disruption via crafted print data.
A buffer overflow vulnerability has been identified in Netatalk versions 2.0.0 through 4.4.2. The issue arises from an off-by-two error in the 'papd' service's 'lp_write()' function, which can lead to a temporary buffer being overwritten. This vulnerability is remotely exploitable, but only under specific conditions when the affected printing configuration is active. The most likely consequence of this vulnerability is a denial-of-service condition.
Users can upgrade to Netatalk version 4.5.0 or later, which includes the necessary patch. Alternatively, version 4.4.2 can be patched manually by applying the 'CVE-2026-44065.patch' available in the Netatalk GitHub repository.
