David Benjamin discovered that OpenSSL incorrectly handled X.400 address processing. A remote attacker could possibly use this issue to read arbitrary memory contents or cause OpenSSL to crash, resulting in a denial of service. (CVE-2023-0286)
Corey Bonnell discovered that OpenSSL incorrectly handled X.509 certificate verification. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. This issue only affected Ubuntu 22.04 LTS and Ubuntu 22.10. (CVE-2022-4203)
Hubert Kario discovered that OpenSSL had a timing based side channel in the OpenSSL RSA Decryption implementation. A remote attacker could possibly use this issue to recover sensitive information. (CVE-2022-4304)
Dawei Wang discovered that OpenSSL incorrectly handled parsing certain PEM data. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. (CVE-2022-4450)
Octavio Galland and Marcel Böhme discovered that OpenSSL incorrectly handled streaming ASN.1 data. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2023-0215)
Marc Schönefeld discovered that OpenSSL incorrectly handled malformed PKCS7 data. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. This issue only affected Ubuntu 22.04 LTS and Ubuntu 22.10. (CVE-2023-0216)
Kurt Roeckx discovered that OpenSSL incorrectly handled validating certain DSA public keys. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. This issue only affected Ubuntu 22.04 LTS and Ubuntu 22.10. (CVE-2023-0217)
Hubert Kario and Dmitry Belyavsky discovered that OpenSSL incorrectly validated certain signatures. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. This issue only affected Ubuntu 22.04 LTS and Ubuntu 22.10. (CVE-2023-0401)
