EulerOS 2.0 SP8 : qemu (EulerOS-SA-2020-2157)

medium Nessus Plugin ID 141005

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the version of the qemu package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

- 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. This flaw allows a guest user to crash the QEMU process, resulting in a denial of service, or the potential execution of arbitrary code with the privileges of the QEMU process on the host.(CVE-2020-14364)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected qemu package.
