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."}],"id":"CVE-2022-4450","lastModified":"2026-10-14T15:17:00.197","metrics":{"cvssMetricV31":[{"cvssData":{"attackComplexity":"LOW","attackVector":"NETWORK","availabilityImpact":"HIGH","baseScore":7.5,"baseSeverity":"HIGH","confidentialityImpact":"NONE","integrityImpact":"NONE","privilegesRequired":"NONE","scope":"UNCHANGED","userInteraction":"NONE","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"exploitabilityScore":3.9,"impactScore":3.6,"source":"nvd@nist.gov","type":"Primary"},{"cvssData":{"attackComplexity":"LOW","attackVector":"NETWORK","availabilityImpact":"HIGH","baseScore":7.5,"baseSeverity":"HIGH","confidentialityImpact":"NONE","integrityImpact":"NONE","privilegesRequired":"NONE","scope":"UNCHANGED","userInteraction":"NONE","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"exploitabilityScore":3.9,"impactScore":3.6,"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","type":"Secondary"}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"id":"CVE-2022-4450","options":[{"exploitation":"none"},{"automatable":"yes"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","timestamp":"2025-04-23T13:26:38.705489Z","version":"2.0.3"}}]},"published":"2023-02-08T20:15:23.973","references":[{"source":"openssl-security@openssl.org","tags":["Patch","Vendor Advisory"],"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","url":"https://security.gentoo.org/glsa/202402-08"},{"source":"openssl-security@openssl.org","tags":["Vendor Advisory"],"url":"https://www.openssl.org/news/secadv/20230207.txt"},{"source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch","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","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","tags":["Vendor Advisory"],"url":"https://www.openssl.org/news/secadv/20230207.txt"},{"source":"0b142b55-0307-4c5a-b3c9-f314f3fb7c5e","url":"https://cert-portal.siemens.com/productcert/html/ssa-203374.html"},{"source":"0b142b55-0307-4c5a-b3c9-f314f3fb7c5e","url":"https://cert-portal.siemens.com/productcert/html/ssa-337522.html"},{"source":"0b142b55-0307-4c5a-b3c9-f314f3fb7c5e","url":"https://cert-portal.siemens.com/productcert/html/ssa-398330.html"},{"source":"0b142b55-0307-4c5a-b3c9-f314f3fb7c5e","url":"https://cert-portal.siemens.com/productcert/html/ssa-556635.html"},{"source":"0b142b55-0307-4c5a-b3c9-f314f3fb7c5e","url":"https://cert-portal.siemens.com/productcert/html/ssa-561322.html"},{"source":"0b142b55-0307-4c5a-b3c9-f314f3fb7c5e","url":"https://cert-portal.siemens.com/productcert/html/ssa-625862.html"},{"source":"0b142b55-0307-4c5a-b3c9-f314f3fb7c5e","url":"https://cert-portal.siemens.com/productcert/html/ssa-699386.html"},{"source":"0b142b55-0307-4c5a-b3c9-f314f3fb7c5e","url":"https://cert-portal.siemens.com/productcert/html/ssa-769027.html"},{"source":"0b142b55-0307-4c5a-b3c9-f314f3fb7c5e","url":"https://cert-portal.siemens.com/productcert/html/ssa-794697.html"},{"source":"0b142b55-0307-4c5a-b3c9-f314f3fb7c5e","url":"https://cert-portal.siemens.com/productcert/html/ssa-879734.html"},{"source":"0b142b55-0307-4c5a-b3c9-f314f3fb7c5e","url":"https://cert-portal.siemens.com/productcert/html/ssa-943925.html"}],"sourceIdentifier":"openssl-security@openssl.org","vulnStatus":"Modified","weaknesses":[{"description":[{"lang":"en","value":"CWE-415"}],"source":"nvd@nist.gov","type":"Primary"},{"description":[{"lang":"en","value":"CWE-415"}],"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","type":"Secondary"}]}
