Where the key or parameters that are being checked have been obtained\nfrom an untrusted source this may lead to a Denial of Service.\n\nThe function DH_check() performs various checks on DH parameters. After fixing\nCVE-2023-3446 it was discovered that a large q parameter value can also trigger\nan overly long computation during some of these checks. A correct q value,\nif present, cannot be larger than the modulus p parameter, thus it is\nunnecessary to perform these checks if q is larger than p.\n\nAn application that calls DH_check() and supplies a key or parameters obtained\nfrom an untrusted source could be vulnerable to a Denial of Service attack.\n\nThe function DH_check() is itself called by a number of other OpenSSL functions.\nAn application calling any of those other functions may similarly be affected.\nThe other functions affected by this are DH_check_ex() and\nEVP_PKEY_param_check().\n\nAlso vulnerable are the OpenSSL dhparam and pkeyparam command line applications\nwhen using the \"-check\" option.\n\nThe OpenSSL SSL/TLS implementation is not affected by this issue.\n\nThe OpenSSL 3.0 and 3.1 FIPS providers are not affected by this issue.","title":"CVE description"}],"product_status":{"recommended":["SUSE Linux Enterprise Server 12 SP2-BCL:libopenssl-devel-1.0.2j-60.104.1.x86_64","SUSE Linux Enterprise Server 12 SP2-BCL:libopenssl1_0_0-1.0.2j-60.104.1.x86_64","SUSE Linux Enterprise Server 12 SP2-BCL:libopenssl1_0_0-32bit-1.0.2j-60.104.1.x86_64","SUSE Linux Enterprise Server 12 SP2-BCL:libopenssl1_0_0-hmac-1.0.2j-60.104.1.x86_64","SUSE Linux Enterprise Server 12 SP2-BCL:libopenssl1_0_0-hmac-32bit-1.0.2j-60.104.1.x86_64","SUSE Linux Enterprise Server 12 SP2-BCL:openssl-1.0.2j-60.104.1.x86_64","SUSE Linux Enterprise Server 12 SP2-BCL:openssl-doc-1.0.2j-60.104.1.noarch"]},"references":[{"category":"external","summary":"CVE-2023-3817","url":"https://www.suse.com/security/cve/CVE-2023-3817"},{"category":"external","summary":"SUSE Bug 1213853 for CVE-2023-3817","url":"https://bugzilla.suse.com/1213853"},{"category":"external","summary":"SUSE Bug 1216922 for CVE-2023-3817","url":"https://bugzilla.suse.com/1216922"}],"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 Server 12 SP2-BCL:libopenssl-devel-1.0.2j-60.104.1.x86_64","SUSE Linux Enterprise Server 12 SP2-BCL:libopenssl1_0_0-1.0.2j-60.104.1.x86_64","SUSE Linux Enterprise Server 12 SP2-BCL:libopenssl1_0_0-32bit-1.0.2j-60.104.1.x86_64","SUSE Linux Enterprise Server 12 SP2-BCL:libopenssl1_0_0-hmac-1.0.2j-60.104.1.x86_64","SUSE Linux Enterprise Server 12 SP2-BCL:libopenssl1_0_0-hmac-32bit-1.0.2j-60.104.1.x86_64","SUSE Linux Enterprise Server 12 SP2-BCL:openssl-1.0.2j-60.104.1.x86_64","SUSE Linux Enterprise Server 12 SP2-BCL:openssl-doc-1.0.2j-60.104.1.noarch"]}],"scores":[{"cvss_v3":{"baseScore":5.3,"baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"products":["SUSE Linux Enterprise Server 12 SP2-BCL:libopenssl-devel-1.0.2j-60.104.1.x86_64","SUSE Linux Enterprise Server 12 SP2-BCL:libopenssl1_0_0-1.0.2j-60.104.1.x86_64","SUSE Linux Enterprise Server 12 SP2-BCL:libopenssl1_0_0-32bit-1.0.2j-60.104.1.x86_64","SUSE Linux Enterprise Server 12 SP2-BCL:libopenssl1_0_0-hmac-1.0.2j-60.104.1.x86_64","SUSE Linux Enterprise Server 12 SP2-BCL:libopenssl1_0_0-hmac-32bit-1.0.2j-60.104.1.x86_64","SUSE Linux Enterprise Server 12 SP2-BCL:openssl-1.0.2j-60.104.1.x86_64","SUSE Linux Enterprise Server 12 SP2-BCL:openssl-doc-1.0.2j-60.104.1.noarch"]}],"threats":[{"category":"impact","date":"2023-08-14T11:06:31Z","details":"moderate"}],"title":"CVE-2023-3817"}]}
