curl: 06: Incomplete fix for CVE-2026-7009: GCC/SecTrust builds silently discard stapled OCSP responses

Summary Curlvtlsappleverify in lib/vtls/apple.c passes the stapled OCSP response to SecTrustSetOCSPResponse only when both HAVEBUILTINAVAILABLE and SUPPORTSSecOCSP are defined. When HAVEBUILTINAVAILABLE is absent, the OCSP buffer is silently discarded. GCC does not support builtinavailable, so th...

OCSP Response Validation Bypass

Bouncy Castle for Java is vulnerable to an OCSP response validation bypass. The vulnerability is due to the failure to properly associate the stapled OCSP response with the intended certificate, which allows an attacker to exploit the validation process by providing a valid OCSP response for a...

openssl: Double-free When Checking OCSP Stapled Response

A flaw was found in OpenSSL. A malicious server can exploit the TLS Online Certificate Status Protocol OCSP stapling feature by sending a specially crafted response. This can trigger a double-free vulnerability in the client's certificate verification process, potentially leading to a Denial of...

openssl: NULL Dereference in Certificate Verification with OCSP Checking

A flaw was found in OpenSSL. When an application is configured with specific non-default settings for certificate verification, including both Online Certificate Status Protocol OCSP response checking and partial chain verification, a NULL dereference can occur.
