{"id":"ALPINE-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":"2026-11-03T06:32:59.286253427Z","published":"2023-09-20T15:15:11.817Z","upstream":["CVE-2023-42464"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2023-42464"}],"affected":[{"package":{"name":"netatalk","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/netatalk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.1"},{"fixed":"3.1.17-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-42464.json"}},{"package":{"name":"netatalk","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/netatalk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.1"},{"fixed":"3.1.17-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-42464.json"}},{"package":{"name":"netatalk","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/netatalk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.1"},{"fixed":"3.1.17-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-42464.json"}},{"package":{"name":"netatalk","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/netatalk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.1"},{"fixed":"3.1.17-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-42464.json"}},{"package":{"name":"netatalk","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/netatalk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.1"},{"fixed":"3.1.17-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-42464.json"}},{"package":{"name":"netatalk","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/netatalk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.1"},{"fixed":"3.1.17-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-42464.json"}},{"package":{"name":"netatalk","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/netatalk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.1"},{"fixed":"3.1.17-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-42464.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
