Cryptographic Application of Elliptic Curve with High Rank

Elliptic curve cryptography is better than traditional cryptography based on RSA and discrete logarithm of finite field in terms of efficiency and security. In this paper, we show how to exploit elliptic curve with high rank, which has not been used in cryptography before, to construct...

CVE-2025-2516 Use of a weak cryptographic key in the signature verification process in WPS Office

The use of a weak cryptographic key pair in the signature verification process in WPS Office Kingsoft on Windows allows an attacker who successfully recovered the private key to sign components. As older versions of WPS Office did not validate the update server's certificate, an...

USN-7363-1 pam-pkcs11 vulnerabilities

Marcus Rückert and Matthias Gerstner discovered that PAM-PKCS11 did not properly handle certain return codes when authentication was not possible. An attacker could possibly use this issue to bypass authentication. This issue only affected Ubuntu 24.04 LTS and Ubuntu 24.10. CVE-2025-24531 It was...

CVE-2025-24032 PAM-PKCS#11 vulnerable to authentication bypass with default value for `cert_policy` (`none`)

PAM-PKCS11 is a Linux-PAM login module that allows a X.509 certificate based user login. Prior to version 0.6.13, if certpolicy is set to none the default value, then pampkcs11 will only check if the user is capable of logging into the token. An attacker may create a different token with the user...

kernel: Kernel panic and system lockup by triggering BUG_ON() in public_key_verify_signature()

A syntax vulnerability was discovered in the kernel's ASN1.1 DER decoder, which could lead to memory corruption or a complete local denial of service through x509 certificate DER files. A local system user could use a specially created key file to trigger BUGON in the publickeyverifysignature...

The vulnerability of the Oracle Fusion Middleware software allows a remote attacker to replace the RSA signature.

The vulnerability of the Oracle Fusion Middleware software exists in the NSS Network Security Services library of Mozilla, which is used by the Oracle iPlanet Web Server. This vulnerability stems from incorrect processing of ASN.1 values in H.509 certificates. Exploiting this vulnerability could...
