Netatalk vulnerabilities

A time-of-check time-of-use (TOCTOU) condition in the ad_flush function in Netatalk 3.0.0 through 4.4.2 involves root-privileged file operations, which may allow a remote attacker to cause limited data modification under specific race conditions.

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.

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.

Netatalk 3.1.2 through 4.4.2 is compiled without FORTIFY_SOURCE, which disables built-in buffer overflow detection at runtime, potentially allowing a remote attacker to cause a minor denial of service via memory errors that would otherwise be caught and safely terminated by runtime protection.

A dead bounds check in the Spotlight RPC unmarshaller in Netatalk 3.0.0 through 4.4.2 results in an unreachable code path that provides no effective bounds protection, which may allow a remote authenticated attacker to obtain limited information via crafted Spotlight RPC requests.

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.

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.

Netatalk 2.2.1 through 4.4.2 calls system() after a failed chdir() without properly handling the error condition, which allows a local privileged user to execute unintended commands or cause a minor service disruption under specific conditions.

An unbounded memory reallocation in the charset conversion code in Netatalk 2.0.0 through 4.4.2 allows a remote authenticated attacker to cause a minor denial of service via crafted character conversion requests.

An integer underflow in the volxlate function in Netatalk 3.0.0 through 4.4.2 allows a local privileged user to obtain limited information, modify limited data, or cause a minor service disruption via crafted volume translation input.
