putty -- multiple security vulnerabilities

Simon Tatham reports: These features are new in PuTTY 0.84: Security issue: fixed a remotely triggerable double-free in RSA key exchange. We don't know of any way it is exploitable to execute code. Minor security issue: fixed a remotely triggerable crash in NIST ECDSA signature verification. An...

Astra Linux – Vulnerability in mbedtls

In Arm Mbed TLS before version 2.19.0, and Arm Mbed Crypto before version 2.0.0, when deterministic ECDSA is enabled, an RNG with insufficient entropy is used for blinding. This may allow an attacker to recover a private key through side-channel attacks if a victim signs the same message multiple...

Astra Linux – Vulnerability in openssl1.0

Normally, in OpenSSL, EC groups always contain a co-factor, and this co-factor is used in code paths that resist side channels. However, in some cases, it is possible to create a group using explicit parameters instead of a named curve. In these cases, the group may not contain a co-factor. This...

Astra Linux – Vulnerability in Node-Elliptic

In the Elliptic package 6.5.6 for Node.js, ECDSA signature malleability occurs because BER-encoded signatures are allowed...

Astra Linux – Vulnerability in nss

During ECDSA signature generation, padding is applied in the nonce to ensure that constant-time scalar multiplication is removed. However, this results in variable-time execution that depends on secret data. This vulnerability affects Firefox versions less than 80, as well as Firefox for Android...

Astra Linux – Vulnerability in bind9

By spoofing the target resolver with responses that have a malformed ECDSA signature, an attacker can trigger a small memory leak. It is possible to gradually erode the available memory to the point where named crashes occur due to lack of resources...

cryptography: cryptography Subgroup Attack Due to Missing Subgroup Validation for SECT Curves

A validation flaw has been discovered in the python cryptography package. This missing validation allows an attacker to provide a public key point P from a small-order subgroup. This can lead to security issues in various situations, such as the most commonly used signature verification ECDSA and...
