The\ncaller is responsible for freeing those buffers. It is possible to construct a\nPEM file that results in 0 bytes of payload data. In this case PEM_read_bio_ex()\nwill return a failure code but will populate the header argument with a pointer\nto a buffer that has already been freed. If the caller also frees this buffer\nthen a double free will occur. This will most likely lead to a crash. 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."}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":3.6},{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":3.6}]},"weaknesses":[{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-415"}]},{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","type":"Secondary","description":[{"lang":"en","value":"CWE-415"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:openssl:openssl:*:*:*:*:*:*:*:*","versionStartIncluding":"1.1.1","versionEndExcluding":"1.1.1t","matchCriteriaId":"DE0061D6-8F81-45D3-B254-82A94915FD08"},{"vulnerable":true,"criteria":"cpe:2.3:a:openssl:openssl:*:*:*:*:*:*:*:*","versionStartIncluding":"3.0.0","versionEndExcluding":"3.0.8","matchCriteriaId":"A6DC5D88-4E99-48F2-8892-610ACA9B5B86"}]}]},{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:stormshield:stormshield_network_security:*:*:*:*:*:*:*:*","versionStartIncluding":"4.0.0","versionEndExcluding":"4.3.16","matchCriteriaId":"F7794B42-8235-4C75-866F-5D0A405F0989"},{"vulnerable":true,"criteria":"cpe:2.3:a:stormshield:stormshield_network_security:*:*:*:*:*:*:*:*","versionStartIncluding":"4.4.0","versionEndExcluding":"4.6.3","matchCriteriaId":"C8A23A5D-928A-4225-9C93-31E5DFE215A7"}]}]}],"references":[{"url":"https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=63bcf189be73a9cc1264059bed6f57974be74a83","source":"openssl-security@openssl.org","tags":["Patch","Vendor Advisory"]},{"url":"https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=bbcf509bd046b34cca19c766bbddc31683d0858b","source":"openssl-security@openssl.org","tags":["Patch","Vendor Advisory"]},{"url":"https://security.gentoo.org/glsa/202402-08","source":"openssl-security@openssl.org"},{"url":"https://www.openssl.org/news/secadv/20230207.txt","source":"openssl-security@openssl.org","tags":["Vendor Advisory"]},{"url":"https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=63bcf189be73a9cc1264059bed6f57974be74a83","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch","Vendor Advisory"]},{"url":"https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=bbcf509bd046b34cca19c766bbddc31683d0858b","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch","Vendor Advisory"]},{"url":"https://psirt.global.sonicwall.com/vuln-detail/SNWLID-2023-0003","source":"af854a3a-2127-422b-91ae-364da2661108"},{"url":"https://security.gentoo.org/glsa/202402-08","source":"af854a3a-2127-422b-91ae-364da2661108"},{"url":"https://www.openssl.org/news/secadv/20230207.txt","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]}]}}]}
