Evaluating Future Air Traffic Management Security

The L-Band Digital Aviation Communication System LDACS aims to modernize communications between the aircraft and the tower. Besides digitizing this type of communication, the contributors also focus on protecting them against cyberattacks. There are several proposals regarding LDACS security, and...

SUSE CVE-2026-34875

An issue was discovered in Mbed TLS through 3.6.5 and TF-PSA-Crypto 1.0.0. A buffer overflow can occur in public key export for FFDH keys...

CVE-2026-35387

A flaw was found in OpenSSH. This vulnerability allows the system to use unintended Elliptic Curve Digital Signature Algorithm ECDSA algorithms. This occurs because the configuration for accepted public key algorithms is misinterpreted, leading to the use of weaker cryptographic methods than...

CVE-2026-34610

A flaw was found in the leancrypto cryptographic library. A remote attacker can exploit an integer overflow vulnerability in the lcx509extractnamesegment function when processing the Common Name CN field of an X.509 certificate. By crafting a specially designed certificate, an attacker can cause...

CVE-2026-28815

A remote attacker can supply a short X-Wing HPKE encapsulated key and trigger an out-of-bounds read in the C decapsulation path, potentially causing a crash or memory disclosure depending on runtime protections. This issue is fixed in swift-crypto version 4.3.1...

Linux Distros Unpatched Vulnerability : CVE-2026-34875

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - An issue was discovered in Mbed TLS through 3.6.5 and TF-PSA-Crypto 1.0.0. A buffer overflow can occur in public key export for FFDH keys. CVE-2026-34875 Note...

Swift Crypto: X-Wing HPKE Decapsulation Accepts Malformed Ciphertext Length

The X-Wing decapsulation path accepts attacker-controlled encapsulated ciphertext bytes without enforcing the required fixed ciphertext length. The decapsulation call is forwarded into a C API, which expects a compile-time fixed-size ciphertext buffer of 1120 bytes. This creates an FFI...

PT-2026-29972

A remote attacker can supply a short X-Wing HPKE encapsulated key and trigger an out-of-bounds read in the C decapsulation path, potentially causing a crash or memory disclosure depending on runtime protections. This issue is fixed in swift-crypto version 4.3.1...

GHSA-MVF2-F6GM-W987 fast-jwt: Incomplete fix for CVE-2023-48223: JWT Algorithm Confusion via Whitespace-Prefixed RSA Public Key

Summary The fix for GHSA-c2ff-88x2-x9pg CVE-2023-48223 is incomplete. The publicKeyPemMatcher regex in fast-jwt/src/crypto.js uses a ^ anchor that is defeated by any leading whitespace in the key string, re-enabling the exact same JWT algorithm confusion attack that the CVE patched. Details The f...

Use of a Broken or Risky Cryptographic Algorithm

Overview fast-jwt is a Fast JSON Web Token implementation Affected versions of this package are vulnerable to Use of a Broken or Risky Cryptographic Algorithm in the performDetectPublicKeyAlgorithms function due to improper handling of leading whitespace in PEM key strings. An attacker can gain...

CVE-2026-35387

OpenSSH before 10.3 is affected by CVE-2026-35387: when listing any ECDSA algorithm in PubkeyAcceptedAlgorithms or HostbasedAcceptedAlgorithms, the client/server may misinterpret this as enabling all ECDSA algorithms. The result is the unintended use of ECDSA keys, with confidentiality impact lis...

Always-Incorrect Control Flow Implementation

Overview Affected versions of this package are vulnerable to Always-Incorrect Control Flow Implementation due to the misinterpretation of the PubkeyAcceptedAlgorithms or HostbasedAcceptedAlgorithms configuration, which causes unintended ECDSA algorithms to be accepted. An attacker can compromise...
