An update for qemu is now available for openEuler-22.03-LTS-SP1 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2024-1312 Final 1.0 1.0 2024-03-22 Initial 2024-03-22 2024-03-22 openEuler SA Tool V1.0 2024-03-22 qemu security update An update for qemu is now available for openEuler-22.03-LTS-SP1. QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed. Security Fix(es): A DMA reentrancy issue leading to a use-after-free error was found in the e1000e NIC emulation code in QEMU. This issue could allow a privileged guest user to crash the QEMU process on the host, resulting in a denial of service.(CVE-2023-3019) A flaw was found in the QEMU built-in VNC server while processing ClientCutText messages. The qemu_clipboard_request() function can be reached before vnc_server_cut_text_caps() was called and had the chance to initialize the clipboard peer, leading to a NULL pointer dereference. This could allow a malicious authenticated VNC client to crash QEMU and trigger a denial of service.(CVE-2023-6683) A stack based buffer overflow was found in the virtio-net device of QEMU. This issue occurs when flushing TX in the virtio_net_flush_tx function if guest features VIRTIO_NET_F_HASH_REPORT, VIRTIO_F_VERSION_1 and VIRTIO_NET_F_MRG_RXBUF are enabled. This could allow a malicious user to overwrite local variables allocated on the stack. Specifically, the `out_sg` variable could be used to read a part of process memory and send it to the wire, causing an information leak.(CVE-2023-6693) An update for qemu is now available for openEuler-22.03-LTS-SP1. openEuler Security has rated this update as having a security impact of medium.
