IKEv1 Denial of Service via RSA-SHA1 (PKCS#1 Version 1.5 Encrypted) authentication payload

...

EUVD-2026-41440

Libreswan, via the function RSAauthenticatehashsignaturepkcs115rsa, did not correctly verify the DER encoding of the ASN.1 digest when the IKEv2 AUTH payload was encoded using RSASSA-PKCS1-v15 RFC 8017. A remote attacker can use a variation on the Bleichenbacher attack to forge the AUTH payload...

CVE-2026-50721

Libreswan, via the function RSAauthenticatehashsignaturerawrsa, did not correctly verify the length of the authentication hash when the SIG payload of an IKEv1 packet was encoded using PKCS 1 RSA Encryption as per RFC 2313. A remote attacker can use a variation on the Bleichenbacher attack to for...

CVE-2026-50721

CVE-2026-50721 concerns Libreswan where the function RSA_authenticate_hash_signature_raw_rsa() does not properly verify the authentication hash length when the SIG payload of an IKEv1 packet is encoded using PKCS#1 RSA Encryption per RFC 2313. This enables a remote attacker to leverage a Bleichen...

CVE-2026-50722

Libreswan is affected by CVE-2026-50722 through RSA_authenticate_hash_signature_pkcs1_1_5_rsa, which fails to properly verify the DER encoding of the ASN.1 digest when the IKEv2 AUTH payload uses RSASSA-PKCS1-v1_5 (RFC 8017). This enables a remote attacker to perform a Bleichenbacher-like variati...

PT-2026-55316

Name of the Vulnerable Software and Affected Versions Libreswan affected versions not specified Description Libreswan fails to correctly verify the DER encoding of the ASN.1 digest within the IKEv2 AUTH payload when using RSASSA-PKCS1-v1 5. This occurs in the RSA authenticate hash signature pkcs1...

Unintended Proxy or Intermediary ('Confused Deputy')

Overview Affected versions of this package are vulnerable to Unintended Proxy or Intermediary 'Confused Deputy' via the uri parameter being passed directly to urllib.request.urlopen, which allows fetching resources using unsupported schemes such as file, ftp, and data. An attacker can access...

CVE-2026-33996 LibJWT has NULL/bounds validation in JWK octet and RSA PSS parsing

LibJWT is a C JSON Web Token Library. Starting in version 3.0.0 and prior to version 3.3.0, the JWK parsing for RSA-PSS did not protect against a NULL value when expecting to parse JSON string values. A specially crafted JWK file could exploit this behavior by using integers in places where the...

CVE-2026-33894

A flaw was found in Forge also called node-forge, a JavaScript implementation of Transport Layer Security. A remote attacker could exploit weaknesses in the RSASSA PKCS1 v1.5 signature verification process. By crafting malicious signatures that include extra data within the ASN structure and do n...

CVE-2026-33894 Forge has signature forgery in RSA-PKCS due to ASN.1 extra field

Forge also called node-forge is a native implementation of Transport Layer Security in JavaScript. Prior to version 1.4.0, RSASSA PKCS1 v1.5 signature verification accepts forged signatures for low public exponent keys e=3. Attackers can forge signatures by stuffing “garbage” bytes within the ASN...

Improper Verification of Cryptographic Signature

Overview org.webjars.npm:node-forge is a WebJar for node-forge. Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature in ASN.1 structures during RSA signature verification. An attacker can bypass signature verification and inject forged signatures by...

ENS DNSSEC Oracle Vulnerable to RSA Signature Forgery via Missing PKCS#1 v1.5 Padding Validation

Impact The RSASHA256Algorithm and RSASHA1Algorithm contracts fail to validate PKCS1 v1.5 padding structure when verifying RSA signatures. The contracts only check if the last 32 or 20 bytes of the decrypted signature match the expected hash. This enables Bleichenbacher's 2006 signature forgery...

CVE-2026-22866

The CVE-2026-22866 entry describes a Bleichenbacher-style RSA signature forgery flaw in Ethereum Name Service (ENS) DNSSEC tooling. In ENS v1.6.2 and earlier, RSASHA256Algorithm and RSASHA1Algorithm do not validate PKCS#1 v1.5 padding correctly and only compare the trailing 32 (or 20) bytes of th...

CVE-2025-62375 go-witness Improper Verification of AWS EC2 Identity Documents

go-witness and witness are Go modules for generating attestations. In go-witness versions 0.8.6 and earlier and witness versions 0.9.2 and earlier the AWS attestor improperly verifies AWS EC2 instance identity documents. Verification can incorrectly succeed when a signature is not present or is...
