An update for qemu is now available for openEuler-20.03-LTS-SP1,openEuler-20.03-LTS-SP2 and openEuler-20.03-LTS-SP3 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2022-1617 Final 1.0 1.0 2022-04-25 Initial 2022-04-25 2022-04-25 openEuler SA Tool V1.0 2022-04-25 qemu security update An update for qemu is now available for openEuler-20.03-LTS-SP1,openEuler-20.03-LTS-SP2 and openEuler-20.03-LTS-SP3. QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed. Security Fix(es): An integer overflow was found in the QEMU implementation of VMWare's paravirtual RDMA device in versions prior to 6.1.0. The issue occurs while handling a "PVRDMA_REG_DSRHIGH" write from the guest due to improper input validation. This flaw allows a privileged guest user to make QEMU allocate a large amount of memory, resulting in a denial of service. The highest threat from this vulnerability is to system availability.(CVE-2021-3607) A flaw was found in the QEMU implementation of VMWare's paravirtual RDMA device in versions prior to 6.1.0. The issue occurs while handling a "PVRDMA_REG_DSRHIGH" write from the guest and may result in a crash of QEMU or cause undefined behavior due to the access of an uninitialized pointer. The highest threat from this vulnerability is to system availability.(CVE-2021-3608) An update for qemu is now available for openEuler-20.03-LTS-SP1,openEuler-20.03-LTS-SP2 and openEuler-20.03-LTS-SP3. openEuler Security has rated this update as having a security impact of medium.
