Si el repositorio de origen es propiedad de un usuario diferente, el usuario que no es de confianza puede reescribir esos archivos vinculados en cualquier momento. La clonaci\u00f3n de repositorios locales har\u00e1 que Git copie o vincule archivos del repositorio de origen al repositorio de destino. Esto acelera significativamente dichos clones locales en comparaci\u00f3n con realizar un clon \\\"adecuado\\\" y ahorra espacio en disco y tiempo de c\u00e1lculo. Al clonar un repositorio ubicado en el mismo disco que es propiedad de un usuario diferente al usuario actual, tambi\u00e9n terminamos creando dichos enlaces f\u00edsicos. Estos archivos seguir\u00e1n siendo propiedad y controlados por el usuario potencialmente no confiable y podr\u00e1n ser reescritos por \u00e9l a voluntad en el futuro. El problema se solucion\u00f3 en las versiones 2.45.1, 2.44.1, 2.43.4, 2.42.2, 2.41.1, 2.40.2 y 2.39.4.\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"security-advisories@github.com\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:C/C:N/I:L/A:L\",\"baseScore\":3.9,\"baseSeverity\":\"LOW\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"HIGH\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"REQUIRED\",\"scope\":\"CHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"LOW\",\"availabilityImpact\":\"LOW\"},\"exploitabilityScore\":0.8,\"impactScore\":2.7}]},\"weaknesses\":[{\"source\":\"security-advisories@github.com\",\"type\":\"Secondary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-281\"}]}],\"references\":[{\"url\":\"http://www.openwall.com/lists/oss-security/2024/05/14/2\",\"source\":\"security-advisories@github.com\"},{\"url\":\"https://github.com/git/git/commit/1204e1a824c34071019fe106348eaa6d88f9528d\",\"source\":\"security-advisories@github.com\"},{\"url\":\"https://github.com/git/git/commit/9e65df5eab274bf74c7b570107aacd1303a1e703\",\"source\":\"security-advisories@github.com\"},{\"url\":\"https://github.com/git/git/security/advisories/GHSA-5rfh-556j-fhgj\",\"source\":\"security-advisories@github.com\"},{\"url\":\"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/S4CK4IYTXEOBZTEM5K3T6LWOIZ3S44AR/\",\"source\":\"security-advisories@github.com\"},{\"url\":\"http://www.openwall.com/lists/oss-security/2024/05/14/2\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://github.com/git/git/commit/1204e1a824c34071019fe106348eaa6d88f9528d\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://github.com/git/git/commit/9e65df5eab274bf74c7b570107aacd1303a1e703\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://github.com/git/git/security/advisories/GHSA-5rfh-556j-fhgj\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/S4CK4IYTXEOBZTEM5K3T6LWOIZ3S44AR/\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"}]}}"
