A flaw was found in the QEMU Guest Agent service for Windows. A local unprivileged user may be able to manipulate the QEMU Guest Agent's Windows installer via repair custom actions to elevate their privileges on the system. • https://bugzilla.redhat.com/show_bug.cgi?id=2167423 https://gitlab.com/qemu-project/qemu/-/commit/07ce178a2b0768eb9e712bb5ad0cf6dc7fcf0158 https://gitlab.com/qemu-project/qemu/-/commit/88288c2a51faa7c795f053fc8b31b1c16ff804c5 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MURWGXDIF2WTDXV36T6HFJDBL632AO7R https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SEOC7SRJWLZSXCND2ADFW6C76ZMTZLE4 https://lists.nongnu.org/archive/html/qemu-devel/2023-03/msg01445 • CWE-250: Execution with Unnecessary Privileges CWE-269: Improper Privilege Management •

A flaw was found in the QEMU implementation of VMWare's paravirtual RDMA device. This flaw allows a crafted guest driver to allocate and initialize a huge number of page tables to be used as a ring of descriptors for CQ and async events, potentially leading to an out-of-bounds read and crash of QEMU. • https://access.redhat.com/security/cve/CVE-2023-1544 https://bugzilla.redhat.com/show_bug.cgi?id=2180364 https://lists.nongnu.org/archive/html/qemu-devel/2023-03/msg00206.html https://security.netapp.com/advisory/ntap-20230511-0005 • CWE-125: Out-of-bounds Read CWE-770: Allocation of Resources Without Limits or Throttling •

An out-of-bounds read flaw was found in the QXL display device emulation in QEMU. The qxl_phys2virt() function does not check the size of the structure pointed to by the guest physical address, potentially reading past the end of the bar space into adjacent pages. A malicious guest user could use this flaw to crash the QEMU process on the host causing a denial of service condition. Se encontró una falla de lectura fuera de los límites en la emulación del dispositivo de visualización QXL en QEMU. La función qxl_phys2virt() no verifica el tamaño de la estructura a la que apunta la dirección física del invitado, lo que potencialmente lee más allá del final del espacio de la barra en páginas adyacentes. • https://bugzilla.redhat.com/show_bug.cgi?id=2148506 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GTVPHLLXJ65BUMFBUUZ35F3J632SLFRK https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/I7J5IRXJYLELW7D43A75LOWRUE5EU54O https://lists.nongnu.org/archive/html/qemu-devel/2022-11/msg04143.html https://security.netapp.com/advisory/ntap-20230127-0012 https://access.redhat.com/security/cve/CVE-2022-4144 • CWE-125: Out-of-bounds Read •

An off-by-one read/write issue was found in the SDHCI device of QEMU. It occurs when reading/writing the Buffer Data Port Register in sdhci_read_dataport and sdhci_write_dataport, respectively, if data_count == block_size. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition. Se encontró un problema de lectura/escritura de uno en uno en el dispositivo SDHCI de QEMU.

A DMA reentrancy issue was found in the Tulip device emulation in QEMU. When Tulip reads or writes to the rx/tx descriptor or copies the rx/tx frame, it doesn't check whether the destination address is its own MMIO address. This can cause the device to trigger MMIO handlers multiple times, possibly leading to a stack or heap overflow. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition.
