This\ncould be exploited by an attacker who has the ability to supply malicious PEM\nfiles for parsing to achieve a denial of service attack.\n\nThe functions PEM_read_bio() and PEM_read() are simple wrappers around\nPEM_read_bio_ex() and therefore these functions are also directly affected.\n\nThese functions are also called indirectly by a number of other OpenSSL\nfunctions including PEM_X509_INFO_read_bio_ex() and\nSSL_CTX_use_serverinfo_file() which are also vulnerable. Some OpenSSL internal\nuses of these functions are not vulnerable because the caller does not free the\nheader argument if PEM_read_bio_ex() returns a failure code. These locations\ninclude the PEM_read_bio_TYPE() functions as well as the decoders introduced in\nOpenSSL 3.0.\n\nThe OpenSSL asn1parse command line application is also impacted by this issue.\n\n\n", "category":"description", "title":"Vulnerability Description" } ], "product_status":{ "fixed":[ "openEuler-22.03-LTS-SP3:openresty-openssl111-1.1.1h-4.oe2203sp3.src", "openEuler-22.03-LTS-SP3:openresty-openssl111-1.1.1h-4.oe2203sp3.x86_64", "openEuler-22.03-LTS-SP3:openresty-openssl111-asan-1.1.1h-4.oe2203sp3.x86_64", "openEuler-22.03-LTS-SP3:openresty-openssl111-asan-devel-1.1.1h-4.oe2203sp3.x86_64", "openEuler-22.03-LTS-SP3:openresty-openssl111-debug-1.1.1h-4.oe2203sp3.x86_64", "openEuler-22.03-LTS-SP3:openresty-openssl111-debug-devel-1.1.1h-4.oe2203sp3.x86_64", "openEuler-22.03-LTS-SP3:openresty-openssl111-devel-1.1.1h-4.oe2203sp3.x86_64", "openEuler-22.03-LTS-SP3:openresty-openssl111-1.1.1h-4.oe2203sp3.aarch64", "openEuler-22.03-LTS-SP3:openresty-openssl111-asan-1.1.1h-4.oe2203sp3.aarch64", "openEuler-22.03-LTS-SP3:openresty-openssl111-asan-devel-1.1.1h-4.oe2203sp3.aarch64", "openEuler-22.03-LTS-SP3:openresty-openssl111-debug-1.1.1h-4.oe2203sp3.aarch64", "openEuler-22.03-LTS-SP3:openresty-openssl111-debug-devel-1.1.1h-4.oe2203sp3.aarch64", "openEuler-22.03-LTS-SP3:openresty-openssl111-devel-1.1.1h-4.oe2203sp3.aarch64" ] }, "remediations":[ { "product_ids":[ "openEuler-22.03-LTS-SP3:openresty-openssl111-1.1.1h-4.oe2203sp3.src", "openEuler-22.03-LTS-SP3:openresty-openssl111-1.1.1h-4.oe2203sp3.x86_64", "openEuler-22.03-LTS-SP3:openresty-openssl111-asan-1.1.1h-4.oe2203sp3.x86_64", "openEuler-22.03-LTS-SP3:openresty-openssl111-asan-devel-1.1.1h-4.oe2203sp3.x86_64", "openEuler-22.03-LTS-SP3:openresty-openssl111-debug-1.1.1h-4.oe2203sp3.x86_64", "openEuler-22.03-LTS-SP3:openresty-openssl111-debug-devel-1.1.1h-4.oe2203sp3.x86_64", "openEuler-22.03-LTS-SP3:openresty-openssl111-devel-1.1.1h-4.oe2203sp3.x86_64", "openEuler-22.03-LTS-SP3:openresty-openssl111-1.1.1h-4.oe2203sp3.aarch64", "openEuler-22.03-LTS-SP3:openresty-openssl111-asan-1.1.1h-4.oe2203sp3.aarch64", "openEuler-22.03-LTS-SP3:openresty-openssl111-asan-devel-1.1.1h-4.oe2203sp3.aarch64", "openEuler-22.03-LTS-SP3:openresty-openssl111-debug-1.1.1h-4.oe2203sp3.aarch64", "openEuler-22.03-LTS-SP3:openresty-openssl111-debug-devel-1.1.1h-4.oe2203sp3.aarch64", "openEuler-22.03-LTS-SP3:openresty-openssl111-devel-1.1.1h-4.oe2203sp3.aarch64" ], "details":"openresty-openssl111 security update", "category":"vendor_fix", "url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2024-2312" } ], "scores":[ { "cvss_v3":{ "baseSeverity":"HIGH", "baseScore":7.5, "vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H", "version":"3.1" }, "products":[ "openEuler-22.03-LTS-SP3:openresty-openssl111-1.1.1h-4.oe2203sp3.src", "openEuler-22.03-LTS-SP3:openresty-openssl111-1.1.1h-4.oe2203sp3.x86_64", "openEuler-22.03-LTS-SP3:openresty-openssl111-asan-1.1.1h-4.oe2203sp3.x86_64", "openEuler-22.03-LTS-SP3:openresty-openssl111-asan-devel-1.1.1h-4.oe2203sp3.x86_64", "openEuler-22.03-LTS-SP3:openresty-openssl111-debug-1.1.1h-4.oe2203sp3.x86_64", "openEuler-22.03-LTS-SP3:openresty-openssl111-debug-devel-1.1.1h-4.oe2203sp3.x86_64", "openEuler-22.03-LTS-SP3:openresty-openssl111-devel-1.1.1h-4.oe2203sp3.x86_64", "openEuler-22.03-LTS-SP3:openresty-openssl111-1.1.1h-4.oe2203sp3.aarch64", "openEuler-22.03-LTS-SP3:openresty-openssl111-asan-1.1.1h-4.oe2203sp3.aarch64", "openEuler-22.03-LTS-SP3:openresty-openssl111-asan-devel-1.1.1h-4.oe2203sp3.aarch64", "openEuler-22.03-LTS-SP3:openresty-openssl111-debug-1.1.1h-4.oe2203sp3.aarch64", "openEuler-22.03-LTS-SP3:openresty-openssl111-debug-devel-1.1.1h-4.oe2203sp3.aarch64", "openEuler-22.03-LTS-SP3:openresty-openssl111-devel-1.1.1h-4.oe2203sp3.aarch64" ] } ], "threats":[ { "details":"High", "category":"impact" } ], "title":"CVE-2022-4450" } ] }
