It is primarily used internally to OpenSSL to support the SMIME, CMS and PKCS7 streaming capabilities, but may also be called directly by end user applications.\n\nThe function receives a `BIO` from the caller, prepends a new `BIO_f_asn1` filter `BIO` onto the front of it to form a `BIO` chain, and then returns the new head of the `BIO` chain to the caller. Under certain conditions, for example if a CMS recipient public key is invalid, the new filter `BIO` is freed and the function returns a `NULL` result indicating a failure. However, in this case, the `BIO` chain is not properly cleaned up and the `BIO` passed by the caller still retains internal pointers to the previously freed filter `BIO`. If the caller then goes on to call `BIO_pop()` on the `BIO` then a use-after-free will occur. This will most likely result in a crash.\n\nThis scenario occurs directly in the internal function `B64_write_ASN1()` which may cause `BIO_new_NDEF()` to be called and will subsequently call `BIO_pop()` on the `BIO`. This internal function is in turn called by the public API functions `PEM_write_bio_ASN1_stream`, `PEM_write_bio_CMS_stream`, `PEM_write_bio_PKCS7_stream`, `SMIME_write_ASN1`, `SMIME_write_CMS` and `SMIME_write_PKCS7`.\n\nOther public API functions that may be impacted by this include `i2d_ASN1_bio_stream`, `BIO_new_CMS`, `BIO_new_PKCS7`, `i2d_CMS_bio_stream` and `i2d_PKCS7_bio_stream`.","affected":[{"package":{"name":"openssl-src","ecosystem":"crates.io","purl":"pkg:cargo/openssl-src"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"111.25.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/02/GHSA-r7jw-wp68-3xch/GHSA-r7jw-wp68-3xch.json"}},{"package":{"name":"openssl-src","ecosystem":"crates.io","purl":"pkg:cargo/openssl-src"},"ranges":[{"type":"SEMVER","events":[{"introduced":"300.0.0"},{"fixed":"300.0.12"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/02/GHSA-r7jw-wp68-3xch/GHSA-r7jw-wp68-3xch.json"}}],"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-0215"},{"type":"WEB","url":"https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=8818064ce3c3c0f1b740a5aaba2a987e75bfbafd"},{"type":"WEB","url":"https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=9816136fe31d92ace4037d5da5257f763aeeb4eb"},{"type":"WEB","url":"https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=c3829dd8825c654652201e16f8a0a0c46ee3f344"},{"type":"WEB","url":"https://psirt.global.sonicwall.com/vuln-detail/SNWLID-2023-0003"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2023-0009.html"},{"type":"WEB","url":"https://security.gentoo.org/glsa/202402-08"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20230427-0007"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20230427-0009"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20240621-0006"},{"type":"WEB","url":"https://www.openssl.org/news/secadv/20230207.txt"}],"database_specific":{"cwe_ids":["CWE-416"],"github_reviewed":true,"github_reviewed_at":"2023-02-08T22:28:34Z","nvd_published_at":"2023-02-08T20:15:00Z","severity":"HIGH"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
