CVE-2022-2127 – Samba: out-of-bounds read in winbind auth_crap
https://notcve.org/view.php?id=CVE-2022-2127
An out-of-bounds read vulnerability was found in Samba due to insufficient length checks in winbindd_pam_auth_crap.c. When performing NTLM authentication, the client replies to cryptographic challenges back to the server. These replies have variable lengths, and Winbind fails to check the lan manager response length. When Winbind is used for NTLM authentication, a maliciously crafted request can trigger an out-of-bounds read in Winbind, possibly resulting in a crash. • https://access.redhat.com/errata/RHSA-2023:6667 https://access.redhat.com/errata/RHSA-2023:7139 https://access.redhat.com/errata/RHSA-2024:0423 https://access.redhat.com/errata/RHSA-2024:0580 https://access.redhat.com/security/cve/CVE-2022-2127 https://bugzilla.redhat.com/show_bug.cgi?id=2222791 https://lists.debian.org/debian-lts-announce/2024/04/msg00015.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/BPCSGND7LO467AJGR5DYBGZLTCGTOBCC https:& • CWE-125: Out-of-bounds Read •
CVE-2023-3354 – Improper i/o watch removal in tls handshake can lead to remote unauthenticated denial of service
https://notcve.org/view.php?id=CVE-2023-3354
A flaw was found in the QEMU built-in VNC server. When a client connects to the VNC server, QEMU checks whether the current number of connections crosses a certain threshold and if so, cleans up the previous connection. If the previous connection happens to be in the handshake phase and fails, QEMU cleans up the connection again, resulting in a NULL pointer dereference issue. This could allow a remote unauthenticated client to cause a denial of service. • https://access.redhat.com/security/cve/CVE-2023-3354 https://bugzilla.redhat.com/show_bug.cgi?id=2216478 https://lists.debian.org/debian-lts-announce/2024/03/msg00012.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/MURWGXDIF2WTDXV36T6HFJDBL632AO7R • CWE-476: NULL Pointer Dereference •
CVE-2023-3269 – Distros-[dirtyvma] privilege escalation via non-rcu-protected vma traversal
https://notcve.org/view.php?id=CVE-2023-3269
A vulnerability exists in the memory management subsystem of the Linux kernel. The lock handling for accessing and updating virtual memory areas (VMAs) is incorrect, leading to use-after-free problems. This issue can be successfully exploited to execute arbitrary kernel code, escalate containers, and gain root privileges. • http://seclists.org/fulldisclosure/2023/Jul/43 http://www.openwall.com/lists/oss-security/2023/07/28/1 http://www.openwall.com/lists/oss-security/2023/08/25/1 http://www.openwall.com/lists/oss-security/2023/08/25/4 https://access.redhat.com/security/cve/CVE-2023-3269 https://bugzilla.redhat.com/show_bug.cgi?id=2215268 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/U6AAA64CUPSMBW6XDTXPQJ3KQWYQ4K7L https://security.netapp.com/advisory • CWE-416: Use After Free •

CVE-2023-2422 – Keycloak: oauth client impersonation
https://notcve.org/view.php?id=CVE-2023-2422
A flaw was found in Keycloak. A Keycloak server configured to support mTLS authentication for OAuth/OpenID clients does not properly verify the client certificate chain. A client that possesses a proper certificate can authorize itself as any other client, therefore, access data that belongs to other clients. Se encontró una falla en Keycloak. Un servidor Keycloak configurado para admitir la autenticación mTLS para clientes OAuth/OpenID no verifica correctamente la cadena de certificados del cliente. • https://access.redhat.com/errata/RHSA-2023:3883 https://access.redhat.com/errata/RHSA-2023:3884 https://access.redhat.com/errata/RHSA-2023:3885 https://access.redhat.com/errata/RHSA-2023:3888 https://access.redhat.com/errata/RHSA-2023:3892 https://access.redhat.com/security/cve/CVE-2023-2422 https://bugzilla.redhat.com/show_bug.cgi?id=2191668 • CWE-295: Improper Certificate Validation •
