DEBIAN-CVE-2026-94418

Under WOLFSSLSMALLCERTVERIFY, ProcessPeerCertParse runs the certificate signature check separately from the parse to keep peak memory down, then merges the two results, but it merged the signature result back only when the parse returned 0, so any parse error hid it. ParseCertRelative reaches its...

Linux Distros Unpatched Vulnerability : CVE-2026-94418

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Under WOLFSSLSMALLCERTVERIFY, ProcessPeerCertParse runs the certificate signature check separately from the parse to keep peak memory down, then merges the two...

Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: gnupg2 (UTSA-2026-090063)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-090063 advisory. A flaw was found in the way certificate signatures could be forged using collisions found in the SHA-1 algorithm. An attacker could use this weakness to create forge...

CVE-2026-54291 Silent channel-binding authentication downgrade via unsupported certificate algorithms

pgjdbc is an open source postgresql JDBC Driver. In releases 42.7.4 through 42.7.11, channelBinding=require connections can be silently downgraded from SCRAM-SHA-256-PLUS with channel binding to plain SCRAM-SHA-256 without it, losing the man-in-the-middle protection the setting is meant to...

Not Failing Securely ('Failing Open')

Overview Affected versions of this package are vulnerable to Not Failing Securely 'Failing Open' in the TlsServerEndpoint process when a server presents an X.509 certificate using a modern signature algorithm lacking traditional naming structures. An attacker can bypass strict client-side...

CVE-2026-55599

phpseclib is a PHP secure communications library. From 0.1.1 until 1.0.30, 2.0.55, and 3.0.54, when an application validates an untrusted X.509 certificate with phpseclib, X509::validateSignature reads a URL out of that certificate's Authority Information Access AIA extension and connects to it...

CVE-2026-5501 Improper Certificate Signature Verification in X.509 Chain Validation Allows Forged Leaf Certificates

wolfSSLX509verifycert in the OpenSSL compatibility layer accepts a certificate chain in which the leaf's signature is not checked, if the attacker supplies an untrusted intermediate with Basic Constraints CA:FALSE that is legitimately signed by a trusted root. An attacker who obtains any leaf...

CVE-2026-5246

CVEs details (CVE-2026-5246) : Affects Cesanta Mongoose up to version 7.20. The vulnerability is in the function mg_tls_verify_cert_signature (mongoose.c) within the P-384 Public Key Handler. Remote exploitation could lead to an authorization bypass. Exploitation is described as complex, and ther...

CVE-2026-5246 Cesanta Mongoose P-384 Public Key mongoose.c mg_tls_verify_cert_signature authorization

A vulnerability was determined in Cesanta Mongoose up to 7.20. Affected is the function mgtlsverifycertsignature of the file mongoose.c of the component P-384 Public Key Handler. Executing a manipulation can lead to authorization bypass. The attack can be executed remotely. Attacks of this nature...

FreeBSD : OpenSSL -- Infinite loop in BN_mod_sqrt parsing certificates (ea05c456-a4fd-11ec-90de-1c697aa5a594)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the ea05c456-a4fd-11ec-90de-1c697aa5a594 advisory. - The BNmodsqrt function, which computes a modular square root, contains a bug that can cause it to loo...

CVE-2022-0778 Infinite loop in BN_mod_sqrt() reachable when parsing certificates

The BNmodsqrt function, which computes a modular square root, contains a bug that can cause it to loop forever for non-prime moduli. Internally this function is used when parsing certificates that contain elliptic curve public keys in compressed form or explicit elliptic curve parameters with a...

Certificate Signature Forging
