cve-2016-8622
Vulnerability from cvelistv5
Published

Modified
2024-08-06 02:27
Severity ?
3.7 (Low) - CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N
Summary
The URL percent-encoding decode function in libcurl before 7.51.0 is called `curl_easy_unescape`. Internally, even if this function would be made to allocate a unscape destination buffer larger than 2GB, it would return that new length in a signed 32 bit integer variable, thus the length would get either just truncated or both truncated and turned negative. That could then lead to libcurl writing outside of its heap based buffer.

Por lo tanto, la longitud se truncar\u00eda o se truncar\u00eda y, adem\u00e1s, se volver\u00eda negativa. Esto podr\u00eda conducir a que libcurl escriba fuera de su b\u00fafer basado en memoria din\u00e1mica (heap).\"}],\"metrics\":{\"cvssMetricV30\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.0\",\"vectorString\":\"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"HIGH\",\"integrityImpact\":\"HIGH\",\"availabilityImpact\":\"HIGH\",\"baseScore\":9.8,\"baseSeverity\":\"CRITICAL\"},\"exploitabilityScore\":3.9,\"impactScore\":5.9},{\"source\":\"secalert@redhat.com\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"3.0\",\"vectorString\":\"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"HIGH\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"LOW\",\"availabilityImpact\":\"NONE\",\"baseScore\":3.7,\"baseSeverity\":\"LOW\"},\"exploitabilityScore\":2.2,\"impactScore\":1.4}],\"cvssMetricV2\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"2.0\",\"vectorString\":\"AV:N/AC:L/Au:N/C:P/I:P/A:P\",\"accessVector\":\"NETWORK\",\"accessComplexity\":\"LOW\",\"authentication\":\"NONE\",\"confidentialityImpact\":\"PARTIAL\",\"integrityImpact\":\"PARTIAL\",\"availabilityImpact\":\"PARTIAL\",\"baseScore\":7.5},\"baseSeverity\":\"HIGH\",\"exploitabilityScore\":10.0,\"impactScore\":6.4,\"acInsufInfo\":false,\"obtainAllPrivilege\":false,\"obtainUserPrivilege\":false,\"obtainOtherPrivilege\":false,\"userInteractionRequired\":false}]},\"weaknesses\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-787\"}]},{\"source\":\"secalert@redhat.com\",\"type\":\"Secondary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-122\"},{\"lang\":\"en\",\"value\":\"CWE-190\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:haxx:libcurl:*:*:*:*:*:*:*:*\",\"versionEndExcluding\":\"7.51.0\",\"matchCriteriaId\":\"09555548-2504-4BE0-97BE-91C99FF1F8AE\"}]}]}],\"references\":[{\"url\":\"http://www.oracle.com/technetwork/security-advisory/cpuoct2018-4428296.html\",\"source\":\"secalert@redhat.com\"},{\"url\":\"http://www.securityfocus.com/bid/94105\",\"source\":\"secalert@redhat.com\",\"tags\":[\"Third Party Advisory\",\"VDB Entry\"]},{\"url\":\"http://www.securitytracker.com/id/1037192\",\"source\":\"secalert@redhat.com\",\"tags\":[\"Third Party Advisory\",\"VDB Entry\"]},{\"url\":\"https://access.redhat.com/errata/RHSA-2018:2486\",\"source\":\"secalert@redhat.com\",\"tags\":[\"Third Party Advisory\"]},{\"url\":\"https://access.redhat.com/errata/RHSA-2018:3558\",\"source\":\"secalert@redhat.com\"},{\"url\":\"https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2016-8622\",\"source\":\"secalert@redhat.com\",\"tags\":[\"Issue Tracking\",\"Patch\",\"Third Party Advisory\"]},{\"url\":\"https://curl.haxx.se/docs/adv_20161102H.html\",\"source\":\"secalert@redhat.com\",\"tags\":[\"Patch\",\"Vendor Advisory\"]},{\"url\":\"https://security.gentoo.org/glsa/201701-47\",\"source\":\"secalert@redhat.com\",\"tags\":[\"Third Party Advisory\"]},{\"url\":\"https://www.tenable.com/security/tns-2016-21\",\"source\":\"secalert@redhat.com\",\"tags\":[\"Third Party Advisory\"]}]}}"
