Improper Certificate Validation

Snowflake drivers are vulnerable to Improper Certificate Validation. The vulnerability is due to improper validation of OCSP responses and treating definitive verification failures as transient, which allows a man-in-the-middle attacker with a revoked certificate and its private key to establish ...

Improper Certificate Validation

Overview org.bouncycastle:bcprov-jdk15on is a Java implementation of cryptographic algorithms. Affected versions of this package are vulnerable to Improper Certificate Validation in the check method of ProvOcspRevocationChecker, which verifies a stapled OCSP response's signature and then treats t...

CVE-2026-58062

In Bouncy Castle for Java before 1.85, Stapled OCSP response accepted without binding to the checked certificate. This issue also affects Bouncy Castle for Java LTS before 2.73.12, and Bouncy Castle for Java FIPS BC-FJA before bc-fips 2.0.2 2.0.X series and 2.1.3 2.1.X series...

CVE-2026-56821

CVE-2026-56821 (Netty) affects Netty’s OcspServerCertificateValidator. Prior to 4.1.136.Final and 4.2.16.Final, it flags an out-of-date OCSP response but does not stop processing, causing an expired GOOD response to be treated as VALID. This can allow an on-path attacker to replay a stale GOOD OC...

USN-8284-1 gnutls28 vulnerabilities

Joshua Rogers discovered that GnuTLS did not properly handle malformed DTLS handshake fragments in certain cases. A remote attacker could possibly use this issue to obtain sensitive information, or cause a denial of service. CVE-2026-33845 Haruto Kimura, Oscar Reparaz, and Zou Dikai discovered th...

CVE-2026-32883: Improper Verification of Cryptographic Signature

Botan is a C++ cryptography library. From version 3.0.0 to before version 3.11.0, during X509 path validation, OCSP responses were checked for an appropriate status code, but critically omitted verifying the signature of the OCSP response itself. This issue has been patched in version 3.11.0...

Local Privilege Escalation

snowflakeconnectorpython is vulnerable to Local Privilege Escalation. The vulnerability is due to the use of the pickle module for serializing OCSP Online Certificate Status Protocol responses, which allows an attacker to craft malicious data that, when deserialized...

Improper Certificate Validation

libcurl.so is vulnerable to Improper Certificate Validation. The vulnerability is caused due to improper handling of OCSP responses, allowing an attacker to exploit the failure to correctly handle certain OCSP response statuses, such as "unauthorized," and mislead the system into accepting an...

USN-7012-1: curl vulnerability

Hiroki Kurosawa discovered that curl incorrectly handled certain OCSP responses. This could result in bad certificates not being checked properly, contrary to expectations...

The vulnerability of the C++ Botan cryptographic library, related to incorrect certificate verification, allows attackers to forge OCSP responses.
