OpenSSH Security Vulnerabilities
OpenSSH OpenBSD Secure Shell is a set of connection tools for secure access to remote computers from the Canadian OpenBSD Project Group. The tools are an open source implementation of the SSH protocol that supports encryption of all transmissions, effectively blocking eavesdropping, connection...
AZL-34764 CVE-2023-45287 affecting package golang for versions less than 1.20.0-1
Before Go 1.20, the RSA based TLS key exchanges used the math/big library, which is not constant time. RSA blinding was applied to prevent timing attacks, but analysis shows this may not have been fully effective. In particular it appears as if the removal of PKCS1 padding may leak timing...

AZL-32051 CVE-2023-49083 affecting package python-cryptography for versions less than 3.3.2-6
cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Calling loadpempkcs7certificates or loadderpkcs7certificates could lead to a NULL-pointer dereference and segfault. Exploitation of this vulnerability poses a serious risk of Denial of Service...
SUSE CVE-2023-6258
A security vulnerability has been identified in the pkcs11-provider, which is associated with Public-Key Cryptography Standards PKCS11. If exploited successfully, this vulnerability could result in a Bleichenbacher-like security flaw, potentially enabling a side-channel attack on PKCS1 1.5...
golang: crypto/tls: slow verification of certificate chains containing large RSA keys
A denial of service vulnerability was found in the Golang Go package caused by an uncontrolled resource consumption flaw. By persuading a victim to use a specially crafted certificate with large RSA keys, a remote attacker can cause a client/server to expend significant CPU time verifying...
CVE-2023-39908
The PKCS11 module of the YubiHSM 2 SDK through 2023.01 does not properly validate the length of specific read operations on object metadata. This may lead to disclosure of uninitialized and previously used memory...
openssh: Remote code execution in ssh-agent PKCS#11 support
A vulnerability was found in OpenSSH. The PKCS11 feature in the ssh-agent in OpenSSH has an insufficiently trustworthy search path, leading to remote code execution if an agent is forwarded to an attacker-controlled system the code in /usr/lib is not necessarily safe for loading into ssh-agent...
Anomaly detection in certificate-based TGT requests
One of the most complex yet effective methods of gaining unauthorized access to corporate network resources is an attack using forged certificates. Attackers create such certificates to fool the Key Distribution Center KDC into granting access to the target companys network. An example of such an...

Google Passkeys: How to create one and when you shouldn't
Google has just brought users closer to a passwordless future. In a recent blog post, the tech giant introduced the option to create and use a safer, more convenient alternative to passwords: Passkeys, a form of digital credential. So, how do they work? Passkeys are generated using public-key...
