An update for qemu is now available for openEuler-22.03-LTS-SP2 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2023-1787 Final 1.0 1.0 2023-11-03 Initial 2023-11-03 2023-11-03 openEuler SA Tool V1.0 2023-11-03 qemu security update An update for qemu is now available for openEuler-22.03-LTS-SP2. QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed. Security Fix(es): A flaw was found in the QEMU built-in VNC server while processing ClientCutText messages. A wrong exit condition may lead to an infinite loop when inflating an attacker controlled zlib buffer in the `inflate_buffer` function. This could allow a remote authenticated client who is able to send a clipboard to the VNC server to trigger a denial of service.(CVE-2023-3255) An update for qemu is now available for openEuler-22.03-LTS-SP2. openEuler Security has rated this update as having a security impact of medium.
