Vulnerability from cvelistv5
Published

Modified
2024-11-15 15:29
Severity ?
6.2 (Medium) - CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
A flaw was found in the RPC library APIs of libvirt. The RPC server deserialization code allocates memory for arrays before the non-negative length check is performed by the C API entry points. Passing a negative length to the g_new0 function results in a crash due to the negative length being treated as a huge positive number. This flaw allows a local, unprivileged user to perform a denial of service attack by causing the libvirt daemon to crash.

El c\u00f3digo de deserializaci\u00f3n del servidor RPC asigna memoria para las matrices antes de que los puntos de entrada de la API de C realicen la verificaci\u00f3n de longitud no negativa. Pasar una longitud negativa a la funci\u00f3n g_new0 provoca un bloqueo debido a que la longitud negativa se trata como un n\u00famero positivo enorme. Esta falla permite que un usuario local sin privilegios realice un ataque de denegaci\u00f3n de servicio provocando la falla del demonio libvirt.\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"secalert@redhat.com\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H\",\"baseScore\":6.2,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":2.5,\"impactScore\":3.6}]},\"weaknesses\":[{\"source\":\"secalert@redhat.com\",\"type\":\"Secondary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-789\"}]}],\"references\":[{\"url\":\"https://access.redhat.com/errata/RHSA-2024:2560\",\"source\":\"secalert@redhat.com\"},{\"url\":\"https://access.redhat.com/errata/RHSA-2024:3253\",\"source\":\"secalert@redhat.com\"},{\"url\":\"https://access.redhat.com/security/cve/CVE-2024-2494\",\"source\":\"secalert@redhat.com\"},{\"url\":\"https://bugzilla.redhat.com/show_bug.cgi?id=2270115\",\"source\":\"secalert@redhat.com\"},{\"url\":\"https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/thread/BKRQXPLPC6B7FLHJXSBQYW7HNDEBW6RJ/\",\"source\":\"secalert@redhat.com\"},{\"url\":\"https://access.redhat.com/errata/RHSA-2024:2560\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://access.redhat.com/errata/RHSA-2024:3253\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://access.redhat.com/security/cve/CVE-2024-2494\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://bugzilla.redhat.com/show_bug.cgi?id=2270115\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://lists.debian.org/debian-lts-announce/2024/04/msg00000.html\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/thread/BKRQXPLPC6B7FLHJXSBQYW7HNDEBW6RJ/\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://security.netapp.com/advisory/ntap-20240517-0009/\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"}]}}"
