CVE-2026-44185

A flaw was found in Apache HTTP Server. This buffer over-read vulnerability occurs when the server processes outbound Online Certificate Status Protocol OCSP requests directed to an attacker-controlled OCSP server. This could allow a remote attacker to read sensitive information from memory or...

gnutls: gnutls: Security bypass allows acceptance of revoked server certificates via crafted OCSP response

A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted Online Certificate Status Protocol OCSP response during a TLS handshake. Due to a logic error in how gnutls processes multi-record OCSP responses, a client with OCSP verification enabl...

tomcat: Apache Tomcat: Certificate revocation bypass due to improper OCSP response validation

A flaw was found in Apache Tomcat. When an Online Certificate Status Protocol OCSP responder is used, the Tomcat Native component, and Tomcat's FFM port of the Tomcat Native code, does not properly verify or check the freshness of the OCSP response. This improper input validation vulnerability...

Linux Distros Unpatched Vulnerability : CVE-2026-42765

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Issue summary: When a partial-chain certificate verification is enabled together with OCSP response checking for the whole chain, a NULL dereference will happen...

NULL Pointer Dereference

Overview Affected versions of this package are vulnerable to NULL Pointer Dereference during OCSP response checking. When a verification chain lacks a self-signed trusted anchor, the issuer of the last certificate is NULL, but the OCSP code accesses the next certificate as the issuer, dereferenci...
