This vulnerability could potentially allow unauthorized read or write access to a Canister's memory. However, exploiting this bug requires the Canister to enable the incremental garbage collector or enhanced orthogonal persistence, which are non-default features in Motoko."},{"lang":"es","value":"El recolector de basura incremental de Motoko se ve afectado por un error de acceso a memoria no inicializada, causado por el uso incorrecto de barreras de escritura en algunas ubicaciones. Esta vulnerabilidad podría permitir el acceso de lectura o escritura no autorizado a la memoria de un contenedor. Sin embargo, para explotar este error, es necesario que el contenedor habilite el recolector de basura incremental o la persistencia ortogonal mejorada, que son funciones no predeterminadas en Motoko."}],"metrics":{"cvssMetricV31":[{"source":"6b35d637-e00f-4228-858c-b20ad6e1d07b","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L","baseScore":5.6,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"LOW","availabilityImpact":"LOW"},"exploitabilityScore":2.2,"impactScore":3.4},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","baseScore":6.5,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":2.5}]},"weaknesses":[{"source":"6b35d637-e00f-4228-858c-b20ad6e1d07b","type":"Secondary","description":[{"lang":"en","value":"CWE-908"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:dfinity:motoko:*:*:*:*:*:*:*:*","versionStartIncluding":"0.9.0","versionEndExcluding":"0.13.4","matchCriteriaId":"00F86BCE-31BC-463B-8CF2-9F581168793D"}]}]}],"references":[{"url":"https://github.com/dfinity/motoko/pull/4677","source":"6b35d637-e00f-4228-858c-b20ad6e1d07b","tags":["Issue Tracking","Patch"]},{"url":"https://github.com/dfinity/motoko/security/advisories/GHSA-9rhg-3qf8-hrv3","source":"6b35d637-e00f-4228-858c-b20ad6e1d07b","tags":["Vendor Advisory"]}]}}]}
