https://notcve.org/view.php?id=CVE-2023-4387
16 Aug 2023 — A use-after-free flaw was found in vmxnet3_rq_alloc_rx_buf in drivers/net/vmxnet3/vmxnet3_drv.c in VMware's vmxnet3 ethernet NIC driver in the Linux Kernel. This issue could allow a local attacker to crash the system due to a double-free while cleaning up vmxnet3_rq_cleanup_all, which could also lead to a kernel information leak problem.

CVE-2023-3223 – Undertow: outofmemoryerror due to @multipartconfig handling
https://notcve.org/view.php?id=CVE-2023-3223
08 Aug 2023 — A flaw was found in undertow. Servlets annotated with @MultipartConfig may cause an OutOfMemoryError due to large multipart content. This may allow unauthorized users to cause remote Denial of Service (DoS) attack. If the server uses fileSizeThreshold to limit the file size, it's possible to bypass the limit by setting the file name in the request to null.

CVE-2022-2127 – Samba: out-of-bounds read in winbind auth_crap
https://notcve.org/view.php?id=CVE-2022-2127
20 Jul 2023 — 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. It was discovered that Samba incorrectly... • https://access.redhat.com/errata/RHSA-2023:6667 • 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
11 Jul 2023 — 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. Gaoning Pan and Xingwei Li discovered that QEMU incorr... • https://access.redhat.com/security/cve/CVE-2023-3354 • 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
06 Jul 2023 — 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. Ruihan Li discovered that the memory management subsystem in the Linux kernel contained a race condition when accessing VMAs in certain conditions, leading to a use-after-free vulnerabilit... • https://github.com/lrh2000/StackRot • CWE-416: Use After Free •

CVE-2023-2422 – Keycloak: oauth client impersonation
https://notcve.org/view.php?id=CVE-2023-2422
28 Jun 2023 — 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 • CWE-295: Improper Certificate Validation •

CVE-2023-2585 – Keycloak: client access via device auth request spoof

28 Jun 2023 — Keycloak's device authorization grant does not correctly validate the device code and client ID. An attacker client could abuse the missing validation to spoof a client consent request and trick an authorization admin into granting consent to a malicious OAuth client or possible unauthorized access to an existing OAuth client.
