The DES and Triple-DES decryption routines in the Heimdal GSSAPI library allow a length-limited write buffer overflow on malloc() allocated memory when presented with a maliciously small packet. This flaw allows a remote user to send specially crafted malicious data to the application, possibly resulting in a denial of service (DoS) attack." } ], "metrics": { "cvssMetricV31": [ { "source": "nvd@nist.gov", "type": "Primary", "cvssData": { "version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "availabilityImpact": "HIGH", "baseScore": 6.5, "baseSeverity": "MEDIUM" }, "exploitabilityScore": 2.8, "impactScore": 3.6 } ] }, "weaknesses": [ { "source": "secalert@redhat.com", "type": "Primary", "description": [ { "lang": "en", "value": "CWE-122" }, { "lang": "en", "value": "CWE-787" } ] } ], "configurations": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:a:samba:samba:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.0.0", "versionEndExcluding": "4.15.11", "matchCriteriaId": "5DEC17A1-7D7E-438F-A7BF-6FA34AD63EC7" }, { "vulnerable": true, "criteria": "cpe:2.3:a:samba:samba:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.16.0", "versionEndExcluding": "4.16.6", "matchCriteriaId": "6601140E-E676-40C8-9700-9B7F9ACEC63C" }, { "vulnerable": true, "criteria": "cpe:2.3:a:samba:samba:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.17.0", "versionEndExcluding": "4.17.2", "matchCriteriaId": "9CD07976-E402-4282-B52A-AC9A6FD27FB5" } ] } ] }, { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:o:fedoraproject:fedora:36:*:*:*:*:*:*:*", "matchCriteriaId": "5C675112-476C-4D7C-BCB9-A2FB2D0BC9FD" }, { "vulnerable": true, "criteria": "cpe:2.3:o:fedoraproject:fedora:37:*:*:*:*:*:*:*", "matchCriteriaId": "E30D0E6F-4AE8-4284-8716-991DFA48CC5D" } ] } ] } ], "references": [ { "url": "http://www.openwall.com/lists/oss-security/2023/02/08/1", "source": "secalert@redhat.com" }, { "url": "https://access.redhat.com/security/cve/CVE-2022-3437", "source": "secalert@redhat.com", "tags": [ "Third Party Advisory" ] }, { "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2137774", "source": "secalert@redhat.com", "tags": [ "Issue Tracking", "Third Party Advisory" ] }, { "url": "https://security.netapp.com/advisory/ntap-20230216-0008/", "source": "secalert@redhat.com" }, { "url": "https://www.samba.org/samba/security/CVE-2022-3437.html", "source": "secalert@redhat.com", "tags": [ "Vendor Advisory" ] } ] }
