{"id":"CVE-2023-33202","details":"Bouncy Castle for Java before 1.73 contains a potential Denial of Service (DoS) issue within the Bouncy Castle org.bouncycastle.openssl.PEMParser class. This class parses OpenSSL PEM encoded streams containing X.509 certificates, PKCS8 encoded keys, and PKCS7 objects. Parsing a file that has crafted ASN.1 data through the PEMParser causes an OutOfMemoryError, which can enable a denial of service attack. (For users of the FIPS Java API: BC-FJA 1.0.2.3 and earlier are affected; BC-FJA 1.0.2.4 is fixed.)","aliases":["GHSA-wjxj-5m7g-mg7q"],"modified":"2026-04-02T09:01:09.392088Z","published":"2023-11-23T16:15:07.273Z","related":["CGA-xfjm-m8mx-2qp9"],"references":[{"type":"WEB","url":"https://github.com/bcgit/bc-java/wiki/CVE%E2%80%902023%E2%80%9033202"},{"type":"WEB","url":"https://bouncycastle.org"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20240125-0001/"},{"type":"EVIDENCE","url":"https://github.com/bcgit/bc-java/wiki/CVE-2023-33202"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/bcgit/bc-java","events":[{"introduced":"0"},{"fixed":"9032821b326fba9fec7528899dfffa79f9f19aef"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"1.73"}]}}],"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"1.0.2.4"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-33202.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
