CVE-2023-29403 (GCVE-0-2023-29403)

Title
Unsafe behavior in setuid/setgid binaries in runtime
Summary
On Unix platforms, the Go runtime does not behave differently when a binary is run with the setuid/setgid bits. This can be dangerous in certain cases, such as when dumping memory state, or assuming the status of standard i/o file descriptors. If a setuid/setgid binary is executed with standard I/O file descriptors closed, opening any files can result in unexpected content being read or written with elevated privileges. Similarly, if a setuid/setgid program is terminated, either via panic or signal, it may leak the contents of its registers.

Esto puede ser peligroso en ciertos casos, como cuando se vuelca el estado de la memoria o se asume el estado de los descriptores de archivos de E/S est\u00e1ndar. Si se ejecuta un binario setuid/setgid con los descriptores de archivos de E/S est\u00e1ndar cerrados, la apertura de cualquier archivo puede provocar que se lea o escriba contenido inesperado con privilegios elevados. De manera similar, si se finaliza un programa setuid/setgid, ya sea por p\u00e1nico o se\u00f1al, puede filtrar el contenido de sus registros.\"}],\"affected\":[{\"source\":\"security@golang.org\",\"affectedData\":[{\"vendor\":\"Go standard library\",\"product\":\"runtime\",\"defaultStatus\":\"unaffected\",\"collectionURL\":\"https://pkg.go.dev\",\"packageName\":\"runtime\",\"versions\":[{\"version\":\"0\",\"lessThan\":\"1.19.10\",\"versionType\":\"semver\",\"status\":\"affected\"},{\"version\":\"1.20.0-0\",\"lessThan\":\"1.20.5\",\"versionType\":\"semver\",\"status\":\"affected\"}]}]}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H\",\"baseScore\":7.8,\"baseSeverity\":\"HIGH\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"REQUIRED\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"HIGH\",\"integrityImpact\":\"HIGH\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":1.8,\"impactScore\":5.9},{\"source\":\"134c704f-9b21-4f2e-91b3-4a467353bcc0\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H\",\"baseScore\":7.8,\"baseSeverity\":\"HIGH\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"REQUIRED\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"HIGH\",\"integrityImpact\":\"HIGH\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":1.8,\"impactScore\":5.9}],\"ssvcV203\":[{\"source\":\"134c704f-9b21-4f2e-91b3-4a467353bcc0\",\"ssvcData\":{\"timestamp\":\"2025-01-06T19:53:25.670138Z\",\"id\":\"CVE-2023-29403\",\"options\":[{\"exploitation\":\"none\"},{\"automatable\":\"no\"},{\"technicalImpact\":\"total\"}],\"role\":\"CISA Coordinator\",\"version\":\"2.0.3\"}}]},\"weaknesses\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-668\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:golang:go:*:*:*:*:*:*:*:*\",\"versionEndExcluding\":\"1.19.10\",\"matchCriteriaId\":\"E17A25CE-A8C9-4F89-916A-BB0327A509C9\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:golang:go:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"1.20.0\",\"versionEndExcluding\":\"1.20.5\",\"matchCriteriaId\":\"53EC811C-49DE-4470-908C-CDC9282EC7FA\"}]}]},{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:fedoraproject:fedora:38:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"CC559B26-5DFC-4B7A-A27C-B77DE755DFF9\"}]}]}],\"references\":[{\"url\":\"https://go.dev/cl/501223\",\"source\":\"security@golang.org\",\"tags\":[\"Patch\"]},{\"url\":\"https://go.dev/issue/60272\",\"source\":\"security@golang.org\",\"tags\":[\"Issue Tracking\"]},{\"url\":\"https://groups.google.com/g/golang-announce/c/q5135a9d924/m/j0ZoAJOHAwAJ\",\"source\":\"security@golang.org\",\"tags\":[\"Mailing List\",\"Release Notes\"]},{\"url\":\"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/NZ2O6YCO2IZMZJELQGZYR2WAUNEDLYV6/\",\"source\":\"security@golang.org\"},{\"url\":\"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/XBS3IIK6ADV24C5ULQU55QLT2UE762ZX/\",\"source\":\"security@golang.org\",\"tags\":[\"Mailing List\"]},{\"url\":\"https://pkg.go.dev/vuln/GO-2023-1840\",\"source\":\"security@golang.org\",\"tags\":[\"Vendor Advisory\"]},{\"url\":\"https://security.gentoo.org/glsa/202311-09\",\"source\":\"security@golang.org\"},{\"url\":\"https://go.dev/cl/501223\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Patch\"]},{\"url\":\"https://go.dev/issue/60272\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Issue Tracking\"]},{\"url\":\"https://groups.google.com/g/golang-announce/c/q5135a9d924/m/j0ZoAJOHAwAJ\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Mailing List\",\"Release Notes\"]},{\"url\":\"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/NZ2O6YCO2IZMZJELQGZYR2WAUNEDLYV6/\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/XBS3IIK6ADV24C5ULQU55QLT2UE762ZX/\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Mailing List\"]},{\"url\":\"https://pkg.go.dev/vuln/GO-2023-1840\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Vendor Advisory\"]},{\"url\":\"https://security.gentoo.org/glsa/202311-09\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://security.netapp.com/advisory/ntap-20241220-0009/\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"}]}}",
