{"id":"UBUNTU-CVE-2023-42464","details":"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.","modified":"2026-03-02T11:56:26.790396Z","published":"2023-09-16T16:00:00Z","related":["USN-6552-1"],"upstream":["CVE-2023-42464"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-42464"},{"type":"REPORT","url":"https://kb.cert.org/vuls/id/408603"},{"type":"REPORT","url":"https://github.com/Netatalk/netatalk/releases/tag/netatalk-3-1-17"},{"type":"REPORT","url":"https://sourceforge.net/p/netatalk/mailman/message/37896632/"},{"type":"REPORT","url":"https://netatalk.sourceforge.io/CVE-2023-42464.php"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6552-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-42464"}],"affected":[{"package":{"name":"netatalk","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/netatalk@3.1.12~ds-4ubuntu0.20.04.3?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.12~ds-4ubuntu0.20.04.3"}]}],"versions":["3.1.12~ds-3","3.1.12~ds-4","3.1.12~ds-4ubuntu0.20.04.1"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"netatalk","binary_version":"3.1.12~ds-4ubuntu0.20.04.3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-42464.json"}},{"package":{"name":"netatalk","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/netatalk@3.1.12~ds-9ubuntu0.22.04.3?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.12~ds-9ubuntu0.22.04.3"}]}],"versions":["3.1.12~ds-9","3.1.12~ds-9build1","3.1.12~ds-9ubuntu0.22.04.1"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"netatalk","binary_version":"3.1.12~ds-9ubuntu0.22.04.3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-42464.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
