An update for qemu is now available for openEuler-22.03-LTS-SP3 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2024-1510 Final 1.0 1.0 2024-04-26 Initial 2024-04-26 2024-04-26 openEuler SA Tool V1.0 2024-04-26 qemu security update An update for qemu is now available for openEuler-22.03-LTS-SP3. QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed. Security Fix(es): A vulnerability in the lsi53c895a device affects the latest version of qemu. A DMA-MMIO reentrancy problem may lead to memory corruption bugs like stack overflow or use-after-free.(CVE-2023-0330) A double free vulnerability was found in QEMU virtio devices (virtio-gpu, virtio-serial-bus, virtio-crypto), where the mem_reentrancy_guard flag insufficiently protects against DMA reentrancy issues. This issue could allow a malicious privileged guest user to crash the QEMU process on the host, resulting in a denial of service or allow arbitrary code execution within the context of the QEMU process on the host.(CVE-2024-3446) 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.(CVE-2024-3447) An update for qemu is now available for openEuler-22.03-LTS-SP3. openEuler Security has rated this update as having a security impact of high.
