https://notcve.org/view.php?id=CVE-2023-3618
12 Jul 2023 — A flaw was found in libtiff. A specially crafted tiff file can lead to a segmentation fault due to a buffer overflow in the Fax3Encode function in libtiff/tif_fax3.c, resulting in a denial of service. It was discovered that LibTIFF could be made to write out of bounds when processing certain malformed image files with the tiffcrop utility. If a user were tricked into opening a specially crafted image file, an attacker could possibly use this issue to cause tiffcrop to crash, resulting in a denial of service... • https://access.redhat.com/security/cve/CVE-2023-3618 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

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 •

11 Jul 2023 — A race condition exists in the Tang server functionality for key generation and key rotation. This flaw results in a small time window where Tang private keys become readable by other processes on the same host. Brian McDermott discovered that Tang incorrectly handled permissions when creating/rotating keys. A local attacker could possibly use this issue to read the keys. • https://access.redhat.com/security/cve/CVE-2023-1672 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

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.

30 Jun 2023 — A hash collision flaw was found in the IPv6 connection lookup table in the Linux kernel’s IPv6 functionality when a user makes a new kind of SYN flood attack. A user located in the local network or with a high bandwidth connection can increase the CPU usage of the server that accepts IPV6 connections up to 95%. It was discovered that the IPv6 implementation in the Linux kernel contained a high rate of hash collisions in connection lookup table. A remote attacker could use this to cause a denial of service. ... • https://bugzilla.redhat.com/show_bug.cgi?id=2175903 • CWE-327: Use of a Broken or Risky Cryptographic Algorithm CWE-400: Uncontrolled Resource Consumption •
