CVE-2019-1798 (GCVE-0-2019-1798)

Vulnerability from cvelistv5 – Published: 2019-04-08 19:30 – Updated: 2024-11-19 19:12
VLAI?
Summary
A vulnerability in the Portable Executable (PE) file scanning functionality of Clam AntiVirus (ClamAV) Software versions 0.101.1 and prior could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The vulnerability is due to a lack of proper input and validation checking mechanisms for PE files sent an affected device. An attacker could exploit this vulnerability by sending malformed PE files to the device running an affected version ClamAV Software. An exploit could allow the attacker to cause an out-of-bounds read condition, resulting in a crash that could result in a denial of service condition on an affected device.

Una vulnerabilidad podr\u00eda permitirle al atacante causar una condici\u00f3n de lectura fuera de l\u00edmites, resultando en un bloqueo que podr\u00eda generar una condici\u00f3n de denegaci\u00f3n de servicio en un dispositivo afectado\"}],\"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:N/I:N/A:H\",\"baseScore\":5.5,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"REQUIRED\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":1.8,\"impactScore\":3.6}],\"cvssMetricV30\":[{\"source\":\"psirt@cisco.com\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"3.0\",\"vectorString\":\"CVSS:3.0/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}],\"cvssMetricV2\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"2.0\",\"vectorString\":\"AV:N/AC:M/Au:N/C:N/I:N/A:P\",\"baseScore\":4.3,\"accessVector\":\"NETWORK\",\"accessComplexity\":\"MEDIUM\",\"authentication\":\"NONE\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"PARTIAL\"},\"baseSeverity\":\"MEDIUM\",\"exploitabilityScore\":8.6,\"impactScore\":2.9,\"acInsufInfo\":false,\"obtainAllPrivilege\":false,\"obtainUserPrivilege\":false,\"obtainOtherPrivilege\":false,\"userInteractionRequired\":true}]},\"weaknesses\":[{\"source\":\"psirt@cisco.com\",\"type\":\"Secondary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-20\"}]},{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-125\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:clamav:clamav:*:*:*:*:*:*:*:*\",\"versionEndIncluding\":\"0.101.1\",\"matchCriteriaId\":\"08665A0F-6D95-4546-BAA9-B4E1335E2056\"}]}]}],\"references\":[{\"url\":\"https://bugzilla.clamav.net/show_bug.cgi?id=12262\",\"source\":\"psirt@cisco.com\",\"tags\":[\"Exploit\",\"Issue Tracking\",\"Patch\",\"Vendor Advisory\"]},{\"url\":\"https://security.gentoo.org/glsa/201904-12\",\"source\":\"psirt@cisco.com\",\"tags\":[\"Third Party Advisory\"]},{\"url\":\"https://bugzilla.clamav.net/show_bug.cgi?id=12262\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Exploit\",\"Issue Tracking\",\"Patch\",\"Vendor Advisory\"]},{\"url\":\"https://security.gentoo.org/glsa/201904-12\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Third Party Advisory\"]}]}}",
