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.","title":"Vulnerability description"}],"product_status":{"fixed":["SUSE Linux Enterprise Live Patching 15 SP4:openssl-1_1-livepatches-0.1-150400.3.3.1.x86_64","openSUSE Leap 15.4:openssl-1_1-livepatches-0.1-150400.3.3.1.x86_64"]},"references":[{"category":"external","summary":"CVE-2023-0286","url":"https://www.suse.com/security/cve/CVE-2023-0286"},{"category":"external","summary":"SUSE Bug 1207533 for CVE-2023-0286","url":"https://bugzilla.suse.com/1207533"},{"category":"external","summary":"SUSE Bug 1207569 for CVE-2023-0286","url":"https://bugzilla.suse.com/1207569"},{"category":"external","summary":"SUSE Bug 1211136 for CVE-2023-0286","url":"https://bugzilla.suse.com/1211136"},{"category":"external","summary":"SUSE Bug 1211503 for CVE-2023-0286","url":"https://bugzilla.suse.com/1211503"},{"category":"external","summary":"SUSE Bug 1213146 for CVE-2023-0286","url":"https://bugzilla.suse.com/1213146"},{"category":"external","summary":"SUSE Bug 1214269 for CVE-2023-0286","url":"https://bugzilla.suse.com/1214269"}],"remediations":[{"category":"vendor_fix","details":"To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or \"zypper patch\".\n","product_ids":["SUSE Linux Enterprise Live Patching 15 SP4:openssl-1_1-livepatches-0.1-150400.3.3.1.x86_64","openSUSE Leap 15.4:openssl-1_1-livepatches-0.1-150400.3.3.1.x86_64"]}],"scores":[{"cvss_v3":{"baseScore":7.4,"baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"products":["SUSE Linux Enterprise Live Patching 15 SP4:openssl-1_1-livepatches-0.1-150400.3.3.1.x86_64","openSUSE Leap 15.4:openssl-1_1-livepatches-0.1-150400.3.3.1.x86_64"]}],"threats":[{"category":"impact","date":"2023-02-23T09:00:21Z","details":"important"}],"title":"CVE-2023-0286"}]}
