Siemens Ruggedcom ROX Improper Neutralization of Special Elements in Output Used by a Downstream Component (CVE-2022-34903)

GnuPG through 2.3.6, in unusual situations where an attacker possesses any secret-key information from a victim's keyring and other constraints e.g., use of GPGME are met, allows signature forgery via injection into the status line. This plugin only works with Tenable.ot. Please visit...

Unity Linux 20.1070e Security Update: poppler (UTSA-2025-993337)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-993337 advisory. NSSCryptoSignBackend.cc in Poppler before 25.04.0 does not verify the adbe.pkcs7.sha1 signatures on documents, resulting in potential signature forgeries. Tenable ha...

DEBIAN-CVE-2025-68972

In GnuPG through 2.4.8, if a signed message has \f at the end of a plaintext line, an adversary can construct a modified message that places additional text after the signed material, such that signature verification of the modified message succeeds although an "invalid armor" message is printed...

cggmp24 and cggmp21 are vulnerable to signature forgery through altered presignatures

Impact This attack is against presignatures used in very specific context: Presignatures + HD wallets derivation: security level reduces to 85 bits \ Previously users could generate a presignature, and then choose a HD derivation path while issuing a partial signature via...

CGGMP21 presignatures can be used in the way that significantly reduces security

This attack is against presignatures used in very specific context: Presignatures + HD wallets derivation: security level reduces to 85 bits \ Previously you could generate a presignature, and then choose a HD derivation path while issuing a partial signature via Presignature::setderivationpath,...
