SSH-Weak-DH

About This tool creates SSH connections to a server and goes through different client configurations to check if the server permits a Diffie-Hellman DH key exchange using a weak group. We aim for our tool to help assess SSH servers for weak DH key exchange settings. Please be aware that this tool...

Astra Linux – Vulnerability in python-cryptography

A flaw was discovered in the python-cryptography package. This issue may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which could result in the exposure of confidential or sensitive data...

CVE-2026-18654

A flaw was found in AWS CLI. This vulnerability, located in the Elastic MapReduce EMR Secure Shell SSH helper commands, involves a lack of entity authentication during key exchange. A remote attacker, positioned between the client and the EMR cluster, could exploit this to intercept SSH sessions...

Linux Distros Unpatched Vulnerability : CVE-2026-18654

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Key exchange without entity authentication in the EMR SSH helper commands in Amazon AWS CLI before 1.45.28 and AWS CLI v2 before 2.35.3 might allow...

Astra Linux – Vulnerability in wpa

In Hostapd 2.10 and earlier, the PKEX code remains active even after a successful PKEX association. An attacker who has successfully bootstrapped public keys with another entity using PKEX in the past will be able to subvert future bootstrapping attempts by passively observing the public keys. By...

Astra Linux – Vulnerability in gnutls28

A vulnerability was identified: the response times for malformed ciphertexts in RSA-PSK ClientKeyExchange differ from those of ciphertexts with correct PKCS1 v1.5 padding...

Astra Linux – Vulnerability in libssh

A flaw was discovered in libssh’s handling of key exchange KEX processes when a client repeatedly sends incorrect KEX guesses. The library fails to free memory during these rekey operations, which can gradually exhaust system memory. This issue can lead to crashes on the client side, especially...

Astra Linux – Vulnerability in gnutls28

A timing side-channel vulnerability in the handling of RSA ClientKeyExchange messages was discovered in GnuTLS. This side-channel can be used to recover the key encrypted in the RSA ciphertext across a network, in a Bleichenbacher-style attack. To successfully decrypt the data, the attacker would...

Astra Linux – Vulnerability in libssh2

In libssh2 before version 1.9.0, the kexmethoddiffiehellmangroupexchangesha256keyexchange function in kex.c contains an integer overflow that could lead to an out-of-bounds read when packets are read from the server. A remote attacker who compromises an SSH server may be able to disclose sensitiv...
