Crypt::DSA versions before 1.21 for Perl reused the nonce across signatures, leading to private-key recovery. Crypt::DSA::sign caches the per-signature nonce material in the Key object without ever clearing it. The first sign on a Key object picks a nonce, and every later sign on that same object...

Azure Linux 3.0 Security Update: CBL-Mariner Releases (CVE-2026-39829)

The version of CBL-Mariner Releases installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2026-39829 advisory. - The RSA and DSA public key parsers did not enforce size limits on key parameters. A crafted...

[SECURITY] Fedora 44 Update: perl-Crypt-DSA-1.20-1.fc44

Crypt::DSA is an implementation of the DSA Digital Signature Algorithm signature verification system. This package provides DSA signing, signature verification, and key generation. DSA Digital Signature Algorithm signatures are no longer considered to be adequate for security. This module should...

SUSE CVE-2026-39829

The RSA and DSA public key parsers did not enforce size limits on key parameters. A crafted public key with an excessively large modulus or DSA parameter could cause several minutes of CPU consumption during signature verification. This could be triggered by unauthenticated clients during public...

Crypt::DSA versions through 1.19 for Perl use 2-args open, allowing existing files to be modified...

CVE-2026-8704

CVE-2026-8704 affects Crypt::DSA for Perl, version up to 1.19, where the 2-argument open function can allow existing files to be modified. This is the underlying root cause described across multiple sources. A fixed version is indicated as later than 1.19 (e.g., 1.20 per release notes), with reme...

CVE-2026-8700

CVE-2026-8700 concerns Crypt::DSA for Perl, where seeds are generated with Perl’s built-in rand. The affected components are Crypt::DSA versions before 1.20. The root cause is the use of a non-cryptographically secure RNG, making seeds predictable for security-sensitive operations. This can under...

CROSS-implementation 安全漏洞

CROSS-implementation is an C-language implementation library for an asymmetric signature algorithm, developed by the CROSS Signature team. There is a security vulnerability in CROSS-implementation, which stems from a integer underflow in the cryptosignopen function, potentially leading to a buffe...

GHSA-W8Q8-93CX-6H7R jsrsasign: Missing cryptographic validation during DSA signing enables private key extraction

Versions of the package jsrsasign before 11.1.1 are vulnerable to Missing Cryptographic Step via the KJUR.crypto.DSA.signWithMessageHash process in the DSA signing implementation. An attacker can recover the private key by forcing r or s to be zero, so the library emits an invalid signature witho...

jsrsasign: Incomplete Comparison Allows DSA Private Key Recovery via Biased Nonce Generation

Versions of the package jsrsasign from 7.0.0 and before 11.1.1 are vulnerable to Incomplete Comparison with Missing Factors via the getRandomBigIntegerZeroToMax and getRandomBigIntegerMinToMax functions in src/crypto-1.1.js; an attacker can recover the private key by exploiting the incorrect...

EUVD-2026-14375

Versions of the package jsrsasign before 11.1.1 are vulnerable to Improper Verification of Cryptographic Signature via the DSA domain-parameter validation in KJUR.crypto.DSA.setPublic and the related DSA/X509 verification flow in src/dsa-2.0.js. An attacker can forge DSA signatures or X.509...
