Package updates are available for Alibaba Cloud Linux 2.1903 that fix the following vulnerabilities: CVE-2020-14364: An out-of-bounds read/write access flaw was found in the USB emulator of the QEMU in versions before 5.2.0. This issue occurs while processing USB packets from a guest when USBDevice 'setup_len' exceeds its 'data_buf[4096]' in the do_token_in, do_token_out routines.
