Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
A vulnerability in the email parsing module Clam AntiVirus (ClamAV) Software versions 0.102.0, 0.101.4 and prior could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The vulnerability is due to inefficient MIME parsing routines that result in extremely long scan times of specially formatted email files. An attacker could exploit this vulnerability by sending a crafted email file to an affected device. An exploit could allow the attacker to cause the ClamAV scanning process to scan the crafted email file indefinitely, resulting in a denial of service condition.

Una explotaci\u00f3n podr\u00eda permitir al atacante causar que el proceso de escaneo de ClamAV escanee el archivo de correo electr\u00f3nico dise\u00f1ado indefinidamente, resultando en una condici\u00f3n de denegaci\u00f3n de servicio.\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"ykramarz@cisco.com\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H\",\"baseScore\":7.5,\"baseSeverity\":\"HIGH\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":3.9,\"impactScore\":3.6},{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H\",\"baseScore\":6.5,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"REQUIRED\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":2.8,\"impactScore\":3.6}],\"cvssMetricV2\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"2.0\",\"vectorString\":\"AV:N/AC:M/Au:N/C:N/I:N/A:C\",\"baseScore\":7.1,\"accessVector\":\"NETWORK\",\"accessComplexity\":\"MEDIUM\",\"authentication\":\"NONE\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"COMPLETE\"},\"baseSeverity\":\"HIGH\",\"exploitabilityScore\":8.6,\"impactScore\":6.9,\"acInsufInfo\":false,\"obtainAllPrivilege\":false,\"obtainUserPrivilege\":false,\"obtainOtherPrivilege\":false,\"userInteractionRequired\":true}]},\"weaknesses\":[{\"source\":\"ykramarz@cisco.com\",\"type\":\"Secondary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-20\"}]},{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-400\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:clamav:clamav:*:*:*:*:*:*:*:*\",\"versionEndIncluding\":\"0.101.4\",\"matchCriteriaId\":\"B0BC0A3F-96C6-40A9-8FD7-FA36F7650256\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:clamav:clamav:0.102.0:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"38845FB7-5C4A-4E4F-81D2-F3338DEDC2BB\"}]}]},{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:cisco:email_security_appliance_firmware:11.1.1-042:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"357904C5-F794-4F22-84A8-9BFDD7801166\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:cisco:email_security_appliance_firmware:11.1.2-023:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"2EECA7F2-8101-445B-A8B3-ACAD1FB6BD8E\"}]}]},{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:canonical:ubuntu_linux:12.04:*:*:*:-:*:*:*\",\"matchCriteriaId\":\"CB66DB75-2B16-4EBF-9B93-CE49D8086E41\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:canonical:ubuntu_linux:14.04:*:*:*:esm:*:*:*\",\"matchCriteriaId\":\"815D70A8-47D3-459C-A32C-9FEACA0659D1\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:debian:debian_linux:8.0:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"C11E6FB0-C8C0-4527-9AA0-CB9B316F8F43\"}]}]}],\"references\":[{\"url\":\"https://bugzilla.clamav.net/show_bug.cgi?id=12380\",\"source\":\"ykramarz@cisco.com\",\"tags\":[\"Exploit\",\"Issue Tracking\",\"Vendor Advisory\"]},{\"url\":\"https://lists.debian.org/debian-lts-announce/2020/02/msg00016.html\",\"source\":\"ykramarz@cisco.com\",\"tags\":[\"Mailing List\",\"Third Party Advisory\"]},{\"url\":\"https://quickview.cloudapps.cisco.com/quickview/bug/CSCvr56010\",\"source\":\"ykramarz@cisco.com\",\"tags\":[\"Third Party Advisory\"]},{\"url\":\"https://security.gentoo.org/glsa/202003-46\",\"source\":\"ykramarz@cisco.com\",\"tags\":[\"Third Party Advisory\"]},{\"url\":\"https://usn.ubuntu.com/4230-2/\",\"source\":\"ykramarz@cisco.com\",\"tags\":[\"Third Party Advisory\"]},{\"url\":\"https://bugzilla.clamav.net/show_bug.cgi?id=12380\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Exploit\",\"Issue Tracking\",\"Vendor Advisory\"]},{\"url\":\"https://lists.debian.org/debian-lts-announce/2020/02/msg00016.html\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Mailing List\",\"Third Party Advisory\"]},{\"url\":\"https://quickview.cloudapps.cisco.com/quickview/bug/CSCvr56010\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Third Party Advisory\"]},{\"url\":\"https://security.gentoo.org/glsa/202003-46\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Third Party Advisory\"]},{\"url\":\"https://usn.ubuntu.com/4230-2/\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Third Party Advisory\"]}]}}"
