A Type Confusion vulnerability was found in the Spotlight RPC functions in afpd in Netatalk 3.1.x before 3.1.17. When parsing Spotlight RPC packets, one encoded data structure is a key-value style dictionary where the keys are character strings, and the values can be any of the supported types in the underlying protocol. Due to a lack of type checking in callers of the dalloc_value_for_key() function, which returns the object associated with a key, a malicious actor may be able to fully control the value of the pointer and theoretically achieve Remote Code Execution on the host. This issue is similar to CVE-2023-34967.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

    (CVE-2023-42464)

The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.04 host has a package installed that is affected by a vulnerability as referenced in the USN-6552-1 advisory.

    Florent Saudel and Arnaud Gatignol discovered that Netatalk incorrectly handled certain specially crafted     Spotlight requests. A remote attacker could possibly use this issue to cause heap corruption and execute     arbitrary code. (CVE-2023-42464)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Debian 10 host has packages installed that are affected by a vulnerability as referenced in the dla-3584 advisory.

    Package        : netatalk     Version        : 3.1.12~ds-3+deb10u4     CVE ID         : CVE-2023-42464     Debian Bug     : 1052087

    Florent Saudel and Arnaud Gatignol discovered a Type Confusion     vulnerability in the Spotlight RPC functions in afpd in Netatalk. When     parsing Spotlight RPC packets, one encoded data structure is a key-value     style dictionary where the keys are character strings, and the values can     be any of the supported types in the underlying protocol. Due to a lack of     type checking in callers of the dalloc_value_for_key() function, which     returns the object associated with a key, a malicious actor may be able to     fully control the value of the pointer and theoretically achieve Remote     Code Execution on the host.

    For Debian 10 buster, this problem has been fixed in version     3.1.12~ds-3+deb10u4.

    We recommend that you upgrade your netatalk packages.

The remote Debian 11 host has a package installed that is affected by multiple vulnerabilities as referenced in the dsa-5503 advisory.

    Multiple security issues were discovered in Netatalk, an implementation of the Apple Filing Protocol (AFP)     for offering file service (mainly) to macOS clients, which may result in the execution of arbitrary code     or information disclosure. For the oldstable distribution (bullseye), these problems have been fixed in     version 3.1.12~ds-8+deb11u1. We recommend that you upgrade your netatalk packages.

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of netatalk installed on the remote host is prior to 3.1.17. It is, therefore, affected by a vulnerability as referenced in the SSA:2023-261-01 advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
