{"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":"2026-08-12T03:51:40.636576267Z","published":"2023-11-23T00:00:00Z","related":["CGA-xfjm-m8mx-2qp9"],"database_specific":{"cna_assigner":"mitre","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/33xxx/CVE-2023-33202.json","unresolved_ranges":[{"extracted_events":[{"fixed":"1.73"}],"source":"DESCRIPTION"}]},"references":[{"type":"WEB","url":"https://bouncycastle.org"},{"type":"WEB","url":"https://github.com/bcgit/bc-java/wiki/CVE%E2%80%902023%E2%80%9033202"},{"type":"WEB","url":"https://github.com/bcgit/bc-java/wiki/CVE-2023-33202"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/33xxx/CVE-2023-33202.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-33202"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20240125-0001/"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/bcgit/bc-java","events":[{"introduced":"0"},{"fixed":"9032821b326fba9fec7528899dfffa79f9f19aef"}],"database_specific":{"source":"CPE_RANGE","cpe":"cpe:2.3:a:bouncycastle:bouncy_castle_for_java:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"1.73"}]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-33202.json"}}],"schema_version":"1.9.0"}
