Netatalk 2.1.0 through 4.4.2 combines multiple errno values using bitwise OR, resulting in incorrect error codes when multiple error conditions occur simultaneously, which may allow a remote attacker to cause a minor service disruption via conditions that trigger incorrect error-handling paths.

A format string argument mismatch in Netatalk 3.0.3 through 4.4.2 allows a remote authenticated attacker to cause a minor denial of service via crafted input that triggers incorrect format string processing.

A missing break statement in DSI OpenSession processing in Netatalk 1.5.0 through 4.4.2 causes a DSIOPT_ATTNQUANT switch case to fall through into DSIOPT_SERVQUANT, resulting in unintended session option handling that may allow a remote attacker to cause a minor service disruption via crafted DSI session options.

An authentication bypass vulnerability in Netatalk 2.2.2 through 4.4.2 allows a remote privileged user to authenticate as an arbitrary user via the admin auth user mechanism.

An SQL injection vulnerability in the MySQL CNID backend in Netatalk 3.1.0 through 4.4.2 allows a remote authenticated attacker to obtain unauthorized access to data, modify data, or cause a denial of service.

A logic error involving bitwise OR operations in Netatalk 3.1.4 through 4.4.2 allows a remote authenticated attacker to inject OS commands and execute arbitrary code.

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.

An out-of-bounds read in ASP session ID handling in Netatalk 1.3 through 4.4.2 allows an adjacent network attacker to obtain limited information or cause a denial of service via a crafted ASP request.

An integer underflow in dsi_writeinit() in Netatalk 1.5.0 through 4.4.2 allows a remote unauthenticated attacker to cause a denial of service via a crafted DSI write request.

An incorrect calculation in the hextoint macro in Netatalk 2.0.0 through 4.4.2 due to improper uppercase character handling allows a remote authenticated attacker to cause limited data modification via crafted hexadecimal input.
