X.400 addresses were parsed as an ASN1_STRING but the public structure definition for GENERAL_NAME incorrectly specified the type of the x400Address field as ASN1_TYPE. This field is subsequently interpreted by the OpenSSL function GENERAL_NAME_cmp as an ASN1_TYPE rather than an ASN1_STRING. When CRL checking is enabled (i.e. the application sets the X509_V_FLAG_CRL_CHECK flag), this vulnerability may allow an attacker to pass arbitrary pointers to a memcmp call, enabling them to read memory contents or enact a denial of service. In most cases, the attack requires the attacker to provide both the certificate chain and CRL, neither of which need to have a valid signature. If the attacker only controls one of these inputs, the other input must already contain an X.400 address as a CRL distribution point, which is uncommon. As such, this vulnerability is most likely to only affect applications which have implemented their own functionality for retrieving CRLs over a network.","state":"PUBLIC","assigner":"openssl-security@openssl.org","published_at":"2023-02-08 20:15:00","updated_at":"2024-02-04

is a type confusion vulnerability relating to X.400 address processing inside an X.509 GeneralName. X.400 addresses were parsed as an ASN1_STRING but the public structure definition for GENERAL_NAME incorrectly specified the type of the x400Address field as ASN1_TYPE. This field is subsequently interpreted by the OpenSSL function GENERAL_NAME_cmp as an ASN1_TYPE rather than an ASN1_STRING. When CRL checking is enabled (i.e. the application sets the X509_V_FLAG_CRL_CHECK flag), this vulnerability may allow an attacker to pass arbitrary pointers to a memcmp call, enabling them to read memory contents or enact a denial of service. In most cases, the attack requires the attacker to provide both the certificate chain and CRL, neither of which need to have a valid signature. If the attacker only controls one of these inputs, the other input must already contain an X.400 address as a CRL distribution point, which is uncommon. As such, this vulnerability is most likely to only affect applications which have implemented their own functionality for retrieving CRLs over a network."}]},"problemtype":{"problemtype_data":[{"description":[{"lang":"eng","value":" type confusion vulnerability"}]}]},"affects":{"vendor":{"vendor_data":[{"vendor_name":"OpenSSL","product":{"product_data":[{"product_name":"OpenSSL","version":{"version_data":[{"version_affected":"<","version_name":"3.0.0","version_value":"3.0.8"},{"version_affected":"<","version_name":"1.1.1","version_value":"1.1.1t"},{"version_affected":"<","version_name":"1.0.2","version_value":"1.0.2zg"}]}}]}}]}},"references":{"reference_data":[{"url":"https://www.openssl.org/news/secadv/20230207.txt","refsource":"MISC","name":"https://www.openssl.org/news/secadv/20230207.txt"},{"url":"https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=2f7530077e0ef79d98718138716bc51ca0cad658","refsource":"MISC","name":"https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=2f7530077e0ef79d98718138716bc51ca0cad658"},{"url":"https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=2c6c9d439b484e1ba9830d8454a34fa4f80fdfe9","refsource":"MISC","name":"https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=2c6c9d439b484e1ba9830d8454a34fa4f80fdfe9"},{"url":"https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=fd2af07dc083a350c959147097003a14a5e8ac4d","refsource":"MISC","name":"https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=fd2af07dc083a350c959147097003a14a5e8ac4d"},{"url":"https://ftp.openbsd.org/pub/OpenBSD/patches/7.2/common/018_x509.patch.sig","refsource":"MISC","name":"https://ftp.openbsd.org/pub/OpenBSD/patches/7.2/common/018_x509.patch.sig"},{"url":"https://ftp.openbsd.org/pub/OpenBSD/LibreSSL/libressl-3.6.2-relnotes.txt","refsource":"MISC","name":"https://ftp.openbsd.org/pub/OpenBSD/LibreSSL/libressl-3.6.2-relnotes.txt"}]},"generator":{"engine":"Vulnogram 0.1.0-dev"},"source":{"discovery":"UNKNOWN"},"credits":[{"lang":"en","value":"David Benjamin (Google)"},{"lang":"en","value":"Hugo Landau"}]},"nvd":{"publishedDate":"2023-02-08 20:15:00","lastModifiedDate":"2024-02-04 09:15:00","problem_types":["CWE-843"],"metrics":{"baseMetricV3":{"cvssV3":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:H","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"NONE","availabilityImpact":"HIGH","baseScore":7.4,"baseSeverity":"HIGH"},"exploitabilityScore":2.2,"impactScore":5.2}},"configurations":{"CVE_data_version":"4.0","nodes":[{"operator":"OR","children":[],"cpe_match":[{"vulnerable":true,"cpe23Uri":"cpe:2.3:a:openssl:openssl:*:*:*:*:*:*:*:*","versionStartIncluding":"3.0.0","versionEndExcluding":"3.0.8","cpe_name":[]},{"vulnerable":true,"cpe23Uri":"cpe:2.3:a:openssl:openssl:*:*:*:*:*:*:*:*","versionStartIncluding":"1.1.1","versionEndExcluding":"1.1.1t","cpe_name":[]},{"vulnerable":true,"cpe23Uri":"cpe:2.3:a:openssl:openssl:*:*:*:*:*:*:*:*","versionStartIncluding":"1.0.2","versionEndExcluding":"1.0.2zg","cpe_name":[]}]},{"operator":"OR","children":[],"cpe_match":[{"vulnerable":true,"cpe23Uri":"cpe:2.3:a:stormshield:stormshield_network_security:*:*:*:*:*:*:*:*","versionStartIncluding":"4.4.0","versionEndExcluding":"4.6.3","cpe_name":[]},{"vulnerable":true,"cpe23Uri":"cpe:2.3:a:stormshield:stormshield_network_security:*:*:*:*:*:*:*:*","versionStartIncluding":"4.0.0","versionEndExcluding":"4.3.16","cpe_name":[]},{"vulnerable":true,"cpe23Uri":"cpe:2.3:a:stormshield:stormshield_network_security:*:*:*:*:*:*:*:*","versionStartIncluding":"3.8.0","versionEndExcluding":"3.11.22","cpe_name":[]},{"vulnerable":true,"cpe23Uri":"cpe:2.3:a:stormshield:stormshield_network_security:*:*:*:*:*:*:*:*","versionStartIncluding":"2.8.0","versionEndExcluding":"3.7.34","cpe_name":[]},{"vulnerable":true,"cpe23Uri":"cpe:2.3:a:stormshield:stormshield_network_security:*:*:*:*:*:*:*:*","versionStartIncluding":"2.7.0","versionEndExcluding":"2.7.11","cpe_name":[]},{"vulnerable":true,"cpe23Uri":"cpe:2.3:a:stormshield:stormshield_management_center:*:*:*:*:*:*:*:*","versionEndExcluding":"3.3.3","cpe_name":[]}]}]}},"legacy_mitre":{"record":null,"notes":[]}}}
