When parsing Spotlight mdssvc RPC packets sent by the client, the core unmarshalling function sl_unpack_loop() did not validate a field in the network packet that contains the count of elements in an array-like structure. By passing 0 as the count value, the attacked function will run in an endless loop consuming 100% CPU. This flaw allows an attacker to issue a malformed RPC request, triggering an infinite loop, resulting in a denial of service condition.","epss":{"date":"2026-11-06","percentile":0.99189,"score":0.62402},"exploits":[],"kev":null,"metrics":[{"score":7.5,"severity":"high","source":"CNA: redhat","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"}],"modifiedAt":1794032006660,"publishedAt":1689864974644,"references":[{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2023:6667"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2023:7139"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2024:0423"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2024:0580"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2024:4101"},{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2023-34966"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2222793"},{"source":"CNA: redhat","tags":[],"url":"https://www.samba.org/samba/security/CVE-2023-34966"},{"source":"ADP: CVE","tags":["vendor-advisory","x_refsource_REDHAT","x_transferred"],"url":"https://access.redhat.com/errata/RHSA-2023:6667"},{"source":"ADP: CVE","tags":["vendor-advisory","x_refsource_REDHAT","x_transferred"],"url":"https://access.redhat.com/errata/RHSA-2023:7139"},{"source":"ADP: CVE","tags":["vendor-advisory","x_refsource_REDHAT","x_transferred"],"url":"https://access.redhat.com/errata/RHSA-2024:0423"},{"source":"ADP: CVE","tags":["vendor-advisory","x_refsource_REDHAT","x_transferred"],"url":"https://access.redhat.com/errata/RHSA-2024:0580"},{"source":"ADP: CVE","tags":["vendor-advisory","x_refsource_REDHAT","x_transferred"],"url":"https://access.redhat.com/errata/RHSA-2024:4101"},{"source":"ADP: CVE","tags":["vdb-entry","x_refsource_REDHAT","x_transferred"],"url":"https://access.redhat.com/security/cve/CVE-2023-34966"},{"source":"ADP: CVE","tags":["issue-tracking","x_refsource_REDHAT","x_transferred"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2222793"},{"source":"ADP: CVE","tags":["x_transferred"],"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/BPCSGND7LO467AJGR5DYBGZLTCGTOBCC/"},{"source":"ADP: CVE","tags":["x_transferred"],"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/OT74M42E6C36W7PQVY3OS4ZM7DVYB64Z/"},{"source":"ADP: CVE","tags":["x_transferred"],"url":"https://security.netapp.com/advisory/ntap-20230731-0010/"},{"source":"ADP: CVE","tags":["x_transferred"],"url":"https://www.debian.org/security/2023/dsa-5477"},{"source":"ADP: CVE","tags":["x_transferred"],"url":"https://www.samba.org/samba/security/CVE-2023-34966"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"As a possible workaround, disable Spotlight by removing all configuration stanzas (\"spotlight=yes|true\") that enable Spotlight ."}],"revision":"c61a2b79d131f62b3e86004075c4913e808b96b6ad265977d00beab9b0559a26","sources":[{"modifiedAt":1794032006660,"name":"CNA: redhat","retrievedAt":1794035300464,"url":"https://www.cve.org/CVERecord?id=CVE-2023-34966"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1794035375260,"url":"https://api.first.org/data/v1/epss?cve=CVE-2023-34966"}],"ssvc":null,"status":"published","title":"Samba: infinite loop in mdssvc rpc service for spotlight","updatedAt":1794035375260}
