[SECURITY] Fedora 39 Update: gnutls-3.8.2-1.fc39

GnuTLS is a secure communications library implementing the SSL, TLS and DTLS protocols and technologies around them. It provides a simple C language application programming interface API to access the secure communications protocols as well as APIs to parse and write X.509, PKCS 12, OpenPGP and...

DEBIAN-CVE-2023-49083

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...

GHSA-JFHM-5GHH-2F97 cryptography vulnerable to NULL-dereference when loading PKCS7 certificates

Summary Calling loadpempkcs7certificates or loadderpkcs7certificates could lead to a NULL-pointer dereference and segfault. PoC Here is a Python code that triggers the issue: python from cryptography.hazmat.primitives.serialization.pkcs7 import loadderpkcs7certificates, loadpempkcs7certificates...

Experts Uncover Passive Method to Extract Private RSA Keys from SSH Connections

A new study has demonstrated that it's possible for passive network attackers to obtain private RSA host keys from a vulnerable SSH server by observing when naturally occurring computational faults that occur while the connection is being established. The Secure Shell SSH protocol is a method for...

SUSE CVE-2023-33202

Bouncy Castle for Java before 1.73 contains a potential Denial of Service DoS issue within the Bouncy Castle org.bouncycastle.openssl.PEMParser class. This class parses OpenSSL PEM encoded streams containing X.509 certificates, PKCS8 encoded keys, and PKCS7 objects. Parsing a file that has crafte...

Observable Discrepancy

Overview jsrsasign is a free pure JavaScript cryptographic library. Affected versions of this package are vulnerable to Observable Discrepancy via the RSA PKCS1.5 or RSAOAEP decryption process. An attacker can decrypt ciphertexts by exploiting the Marvin security flaw. Exploiting this vulnerabili...

Weak Encryption

upydev is vulnerable to Weak Encryption. The vulnerability is due to PKCS 1v1.5 padding used in the RSA algorithm. This could lead to a Bleichenbacher attack...

opensc: buffer overrun vulnerability in pkcs15 cardos_have_verifyrc_package

A vulnerability was found in OpenSC. This issue causes a buffer overrun in the pkcs15 cardoshaveverifyrcpackage. This flaw allows an attacker to supply a smart card package with a malformed ASN1 context. The cardoshaveverifyrcpackage function scans the ASN1 buffer for two tags, where the remainin...

The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path, leading to remote code execution (CVE-2023-38408)

The PKCS11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path, leading to remote code execution if an agent is forwarded to an attacker-controlled system. Code in /usr/lib is not necessarily safe for loading into ssh-agent. NOTE: this issue exists because o...
