An update for qemu is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP3 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2022-1690 Final 1.0 1.0 2022-06-02 Initial 2022-06-02 2022-06-02 openEuler SA Tool V1.0 2022-06-02 qemu security update An update for qemu is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP3. QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed. Security Fix(es): sd_wp_addr in hw/sd/sd.c in QEMU 4.2.0 uses an unvalidated address, which leads to an out-of-bounds read during sdhci_write() operations. A guest OS user can crash the QEMU process.(CVE-2020-13253) An infinite loop flaw was found in the e1000 NIC emulator of the QEMU. This issue occurs while processing transmits (tx) descriptors in process_tx_desc if various descriptor fields are initialized with invalid values. This flaw allows a guest to consume CPU cycles on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability.(CVE-2021-20257) An update for qemu is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP3. openEuler Security has rated this update as having a security impact of medium. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.
