EulerOS Virtualization 2.11.0 : util-linux (EulerOS-SA-2024-2203)

high Nessus Plugin ID 205903

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the util-linux package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

 QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed.QEMU has two operating modes: Full system emulation. In this mode, QEMU emulates a full system (for example a PC), including one or several processors and various peripherals. It can be used to launch different Operating Systems without rebooting the PC or to debug system code. User mode emulation. In this mode, QEMU can launch processes compiled for one CPU on another CPU. It can be used to launch the Wine Windows API emulator (https://www.winehq.org) or to ease cross-compilation and cross-debugging.You can refer to https://www.qemu.org for more infortmation.A heap based buffer overflow was found in the SDHCI device emulation of QEMU. The bug is triggered when both `s-data_count` and the size of `s-fifo_buffer` are set to 0x200, leading to an out-of-bound access. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition.(CVE-2024-3447 )

This issue could allow a malicious privileged guest user to crash the QEMU process on the host, resulting in a denial of service or allow arbitrary code execution within the context of the QEMU process on the host.(CVE-2024-3446)

Tenable has extracted the preceding description block directly from the EulerOS Virtualization util-linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected util-linux packages.
