CVE-2022-24771 Improper Verification of Cryptographic Signature in node-forge

Forge also called node-forge is a native implementation of Transport Layer Security in JavaScript. Prior to version 1.3.0, RSA PKCS1 v1.5 signature verification code is lenient in checking the digest algorithm structure. This can allow a crafted structure that steals padding bytes and uses...

CVE-2022-24771

CVE-2022-24771 affects Forge (node-forge). Prior to 1.3.0, RSA PKCS#1 v1.5 signature verification is lenient, allowing a crafted DigestInfo structure to steal padding bytes and forge a signature when a low public exponent is used. The issue is fixed in node-forge 1.3.0. Practical impact, as state...

Breaking RSA through Insufficiently Random Primes

Basically, the SafeZone library doesnt sufficiently randomize the two prime numbers it used to generate RSA keys. Theyre too close to each other, which makes them vulnerable to recovery. There arent many weak keys out there, but there are some: So far, Böck has identified only a handful of keys i...

CVE-2022-27191

A broken cryptographic algorithm flaw was found in golang.org/x/crypto/ssh. This issue causes a client to fail authentication with RSA keys to servers that reject signature algorithms based on SHA-2, enabling an attacker to crash the server, resulting in a loss of availability...

Debian DSA-5103-1 : openssl - security update

The remote Debian 10 / 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5103 advisory. Tavis Ormandy discovered that the BNmodsqrt function of OpenSSL could be tricked into an infinite loop. This could result in denial of service via malformed...
