bouncycastle: BC-JAVA: PKIX draft CompositeVerifier accepts empty signature sequence as valid

A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcpkix. The PKIX draft CompositeVerifier implementation improperly accepts an empty signature sequence as a valid cryptographic signature. This issue allows a remote attacker to bypass signature verification mechanisms, potentially...

CVE-2026-69248

Cryptography (Python) prior to 49.0.0 may accept a leaf certificate with a wildcard SAN (*.example.com) when a constrained sub-CA permits foo.example.com, due to DNSConstraint::matches treating a wildcard as matching the permitted constraint. This can allow escaping to sibling names (e.g., bar.ex...

CVE-2026-69248 python-cryptography verifier accepts wildcard DNS names allowing escape from permittedSubtrees

cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. In versions 45.0.0 through 48.0.0, if an intermediate constrained CA permits the DNS name foo.example.com, and the leaf certificate has a wildcard in its DNS SAN of .example.com,...

CVE-2026-0392

eParakstītājs 3.0 for Windows prior to 1.10.0 is vulnerable: its auto-update uses an unauthenticated/integrity-free channel. The client fetches an XML update descriptor over TLS while accepting any certificate, with no verification of the descriptor’s digital signature, no Authenticode/signature ...

CVE-2026-0392 eParakstītājs 3.0 for Windows – remote code execution via unauthenticated auto-update

eParakstītājs 3.0 for Windows before version 1.10.0 retrieves and executes its automatic updates over a channel that is not authenticated or integrity-protected. On each launch the application fetches an update descriptor XML over TLS but accepts any TLS certificate a permissive TrustManager and ...

Memory Allocation with Excessive Size Value
