CVE-2023-0361 – gnutls: timing side-channel in the TLS RSA key exchange code
https://notcve.org/view.php?id=CVE-2023-0361
A timing side-channel in the handling of RSA ClientKeyExchange messages was discovered in GnuTLS. This side-channel can be sufficient to recover the key encrypted in the RSA ciphertext across a network in a Bleichenbacher style attack. To achieve a successful decryption the attacker would need to send a large amount of specially crafted messages to the vulnerable server. By recovering the secret from the ClientKeyExchange message, the attacker would be able to decrypt the application data exchanged over that connection. A timing side-channel vulnerability was found in RSA ClientKeyExchange messages in GnuTLS. • https://access.redhat.com/security/cve/CVE-2023-0361 https://github.com/tlsfuzzer/tlsfuzzer/pull/679 https://gitlab.com/gnutls/gnutls/-/issues/1050 https://lists.debian.org/debian-lts-announce/2023/02/msg00015.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UFIA3X4IZ3CW7SRQ2UHNHNPMRIAWF2FI https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WS4KVDOG6QTALWHC2QE4Y7VPDRMLTRWQ https://lists.fedoraproject.org/archives/list/package& • CWE-203: Observable Discrepancy •
CVE-2023-0494 – X.Org Server DeepCopyPointerClasses Use-After-Free Local Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2023-0494
A vulnerability was found in X.Org. This issue occurs due to a dangling pointer in DeepCopyPointerClasses that can be exploited by ProcXkbSetDeviceInfo() and ProcXkbGetDeviceInfo() to read and write into freed memory. This can lead to local privilege elevation on systems where the X server runs privileged and remote code execution for ssh X forwarding sessions. This vulnerability allows local attackers to escalate privileges on affected installations of X.Org Server. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the DeepCopyPointerClasses function. • https://bugzilla.redhat.com/show_bug.cgi?id=2165995 https://gitlab.freedesktop.org/xorg/xserver/-/commit/0ba6d8c37071131a49790243cdac55392ecf71ec https://lists.x.org/archives/xorg-announce/2023-February/003320.html https://security.gentoo.org/glsa/202305-30 https://access.redhat.com/security/cve/CVE-2023-0494 • CWE-416: Use After Free •
CVE-2022-42439 – IBM App Connect Enterprise information disclosure

CVE-2022-41731 – IBM Watson Knowledge Catalog on Cloud Pak SQL injection
https://notcve.org/view.php?id=CVE-2022-41731
IBM Watson Knowledge Catalog on Cloud Pak for Data 4.5.0 is vulnerable to SQL injection. A remote attacker could send specially crafted SQL statements, which could allow the attacker to view, add, modify or delete information in the back-end database.

CVE-2022-3560 – pesign: Local privilege escalation on pesign systemd service
https://notcve.org/view.php?id=CVE-2022-3560
A flaw was found in pesign. The pesign package provides a systemd service used to start the pesign daemon. This service unit runs a script to set ACLs for /etc/pki/pesign and /run/pesign directories to grant access privileges to users in the 'pesign' group. However, the script doesn't check for symbolic links. This could allow an attacker to gain access to privileged files and directories via a path traversal attack. • https://bugzilla.redhat.com/show_bug.cgi?id=2135420#c0 https://access.redhat.com/security/cve/CVE-2022-3560 https://bugzilla.redhat.com/show_bug.cgi?id=2135420 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
