Ubuntu 20.04 LTS / 22.04 LTS / 23.04 : Netatalk vulnerability (USN-6552-1)

critical Nessus Plugin ID 186773

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

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.

 - 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.
 (CVE-2023-42464)

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

Solution

Update the affected netatalk package.
