CVE-2024-45819 – libxl leaks data to PVH guests via ACPI tables
https://notcve.org/view.php?id=CVE-2024-45819
19 Dec 2024 — PVH guests have their ACPI tables constructed by the toolstack. The construction involves building the tables in local memory, which are then copied into guest memory. While actually used parts of the local memory are filled in correctly, excess space that is being allocated is left with its prior contents. PVH guests have their ACPI tables constructed by the toolstack. The construction involves building the tables in local memory, which are then copied into guest memory. • https://xenbits.xenproject.org/xsa/advisory-464.html • CWE-276: Incorrect Default Permissions •
CVE-2024-45818 – Deadlock in x86 HVM standard VGA handling
https://notcve.org/view.php?id=CVE-2024-45818
19 Dec 2024 — The hypervisor contains code to accelerate VGA memory accesses for HVM guests, when the (virtual) VGA is in "standard" mode. Locking involved there has an unusual discipline, leaving a lock acquired past the return from the function that acquired it. This behavior results in a problem when emulating an instruction with two memory accesses, both of which touch VGA memory (plus some further constraints which aren't relevant here). When emulating the 2nd access, the lock that is already being held would be att... • https://xenbits.xenproject.org/xsa/advisory-463.html • CWE-667: Improper Locking •
CVE-2024-3447 – Qemu: sdhci: heap buffer overflow in sdhci_write_dataport()
https://notcve.org/view.php?id=CVE-2024-3447
14 Nov 2024 — A heap-based buffer overflow was found in the SDHCI device emulation of QEMU. The bug is triggered when both `s->data_count` and the size of `s->fifo_buffer` are set to 0x200, leading to an out-of-bound access. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition. • https://access.redhat.com/security/cve/CVE-2024-3447 • CWE-122: Heap-based Buffer Overflow •
CVE-2023-34049 – Salt security advisory release - 2023-OCT-27
https://notcve.org/view.php?id=CVE-2023-34049
14 Nov 2024 — The Salt-SSH pre-flight option copies the script to the target at a predictable path, which allows an attacker to force Salt-SSH to run their script. If an attacker has access to the target VM and knows the path to the pre-flight script before it runs they can ensure Salt-SSH runs their script with the privileges of the user running Salt-SSH. Do not make the copy path on the target predictable and ensure we check return codes of the scp command if the copy fails. The Salt-SSH pre-flight option copies the sc... • https://saltproject.io/security-announcements/2023-10-27-advisory •

CVE-2024-45817 – x86: Deadlock in vlapic_error()
https://notcve.org/view.php?id=CVE-2024-45817
25 Sep 2024 — In x86's APIC (Advanced Programmable Interrupt Controller) architecture, error conditions are reported in a status register. Furthermore, the OS can opt to receive an interrupt when a new error occurs. It is possible to configure the error interrupt with an illegal vector, which generates an error when an error interrupt is raised. This case causes Xen to recurse through vlapic_error(). The recursion itself is bounded; errors accumulate in the the status register and only generate an interrupt when a new st... • https://xenbits.xenproject.org/xsa/advisory-462.html • CWE-209: Generation of Error Message Containing Sensitive Information •
CVE-2024-31146 – PCI device pass-through with shared resources
https://notcve.org/view.php?id=CVE-2024-31146
25 Sep 2024 — When multiple devices share resources and one of them is to be passed through to a guest, security of the entire system and of respective guests individually cannot really be guaranteed without knowing internals of any of the involved guests. Therefore such a configuration cannot really be security-supported, yet making that explicit was so far missing. Resources the sharing of which is known to be problematic include, but are not limited to - - PCI Base Address Registers (BARs) of multiple devices mapping ... • https://xenbits.xenproject.org/xsa/advisory-461.html • CWE-400: Uncontrolled Resource Consumption •
CVE-2024-31145 – error handling in x86 IOMMU identity mapping
https://notcve.org/view.php?id=CVE-2024-31145
25 Sep 2024 — Certain PCI devices in a system might be assigned Reserved Memory Regions (specified via Reserved Memory Region Reporting, "RMRR") for Intel VT-d or Unity Mapping ranges for AMD-Vi. These are typically used for platform tasks such as legacy USB emulation. Since the precise purpose of these regions is unknown, once a device associated with such a region is active, the mappings of these regions need to remain continuouly accessible by the device. In the logic establishing these mappings, error handling was fl... • https://xenbits.xenproject.org/xsa/advisory-460.html • CWE-400: Uncontrolled Resource Consumption •

CVE-2024-7348 – PostgreSQL relation replacement during pg_dump executes arbitrary SQL
https://notcve.org/view.php?id=CVE-2024-7348
08 Aug 2024 — Time-of-check Time-of-use (TOCTOU) race condition in pg_dump in PostgreSQL allows an object creator to execute arbitrary SQL functions as the user running pg_dump, which is often a superuser. The attack involves replacing another relation type with a view or foreign table. The attack requires waiting for pg_dump to start, but winning the race condition is trivial if the attacker retains an open transaction. Versions before PostgreSQL 16.4, 15.8, 14.13, 13.16, and 12.20 are affected. A vulnerability was foun... • https://www.postgresql.org/support/security/CVE-2024-7348 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
