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.

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.

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

  - This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations     of Synology DiskStation Manager. Authentication is not required to exploit this vulnerablity. The specific     flaw exists within the processing of DSI structures in Netatalk. The issue results from the lack of proper     validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can     leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-12326.
    (CVE-2021-31439)

  - This vulnerability allows remote attackers to execute arbitrary code on affected installations of     Netatalk. Authentication is not required to exploit this vulnerability. The specific flaw exists within     the ad_addcomment function. The issue results from the lack of proper validation of the length of user-     supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this     vulnerability to execute code in the context of root. Was ZDI-CAN-15876. (CVE-2022-0194)

  - This vulnerability allows remote attackers to execute arbitrary code on affected installations of     Netatalk. Authentication is not required to exploit this vulnerability. The specific flaw exists within     the parse_entries function. The issue results from the lack of proper error handling when parsing     AppleDouble entries. An attacker can leverage this vulnerability to execute code in the context of root.
    Was ZDI-CAN-15819. (CVE-2022-23121)

  - This vulnerability allows remote attackers to execute arbitrary code on affected installations of     Netatalk. Authentication is not required to exploit this vulnerability. The specific flaw exists within     the setfilparams function. The issue results from the lack of proper validation of the length of user-     supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this     vulnerability to execute code in the context of root. Was ZDI-CAN-15837. (CVE-2022-23122)

  - This vulnerability allows remote attackers to disclose sensitive information on affected installations of     Netatalk. Authentication is not required to exploit this vulnerability. The specific flaw exists within     the getdirparams method. The issue results from the lack of proper validation of user-supplied data, which     can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction     with other vulnerabilities to execute arbitrary code in the context of root. Was ZDI-CAN-15830.
