Summary
openssl1.0 vulnerabilities
Details

It was discovered that checking excessively long DH keys or parameters may be very slow. A remote attacker could possibly use this issue to cause OpenSSL to consume resources, resulting in a denial of service. (CVE-2023-3446)

After the fix for CVE-2023-3446 Bernd Edlinger discovered that a large q parameter value can also trigger an overly long computation during some of these checks. A remote attacker could possibly use this issue to cause OpenSSL to consume resources, resulting in a denial of service. (CVE-2023-3817)

David Benjamin discovered that generating excessively long X9.42 DH keys or checking excessively long X9.42 DH keys or parameters may be very slow. A remote attacker could possibly use this issue to cause OpenSSL to consume resources, resulting in a denial of service. (CVE-2023-5678)

Bahaa Naamneh discovered that processing a maliciously formatted PKCS12 file may lead OpenSSL to crash leading to a potential Denial of Service attack. (CVE-2024-0727)
