The qemu_clipboard_request() function can be reached before vnc_server_cut_text_caps() was called and had the chance to initialize the clipboard peer, leading to a NULL pointer dereference. This could allow a malicious authenticated VNC client to crash QEMU and trigger a denial of service."},{"lang":"es","value":"Se encontró una falla en el servidor QEMU built-in VNC al procesar mensajes ClientCutText. Se puede acceder a la función qemu_clipboard_request() antes de que se llamara a vnc_server_cut_text_caps() y tuviera la oportunidad de inicializar el par del portapapeles, lo que lleva a una desreferencia del puntero NULL. Esto podría permitir que un cliente VNC autenticado malicioso bloquee QEMU y provoque una denegación de servicio."}],"metrics":{"cvssMetricV31":[{"source":"secalert@redhat.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","baseScore":6.5,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":3.6},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","baseScore":6.5,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":3.6}]},"weaknesses":[{"source":"secalert@redhat.com","type":"Secondary","description":[{"lang":"en","value":"CWE-476"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-476"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:qemu:qemu:*:*:*:*:*:*:*:*","versionStartIncluding":"6.1.0","versionEndExcluding":"8.2.2","matchCriteriaId":"C0232DBC-5896-4EC7-AEE7-595BBD67A5C7"}]}]},{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:redhat:enterprise_linux:8.0:*:*:*:*:*:*:*","matchCriteriaId":"F4CFF558-3C47-480D-A2F0-BABF26042943"},{"vulnerable":true,"criteria":"cpe:2.3:o:redhat:enterprise_linux:9.0:*:*:*:*:*:*:*","matchCriteriaId":"7F6FB57C-2BC7-487C-96DD-132683AEB35D"}]}]}],"references":[{"url":"https://access.redhat.com/errata/RHSA-2024:2135","source":"secalert@redhat.com","tags":["Third Party Advisory"]},{"url":"https://access.redhat.com/errata/RHSA-2024:2962","source":"secalert@redhat.com","tags":["Third Party Advisory"]},{"url":"https://access.redhat.com/security/cve/CVE-2023-6683","source":"secalert@redhat.com","tags":["Third Party Advisory"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2254825","source":"secalert@redhat.com","tags":["Issue Tracking","Patch"]},{"url":"https://access.redhat.com/errata/RHSA-2024:2135","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Third Party Advisory"]},{"url":"https://access.redhat.com/errata/RHSA-2024:2962","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Third Party Advisory"]},{"url":"https://access.redhat.com/security/cve/CVE-2023-6683","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Third Party Advisory"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2254825","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Issue Tracking","Patch"]},{"url":"https://security.netapp.com/advisory/ntap-20240223-0001/","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Third Party Advisory"]}]}}]}
