Alpine: multiple qemu packages: security update to 6.1.1-r0

high Tenable Self-Hosted Container Security Plugin ID 406793

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- An incorrect default permissions vulnerability was found in the mig-controller. Due to an incorrect
cluster namespaces handling an attacker may be able to migrate a malicious workload to the target cluster,
impacting confidentiality, integrity, and availability of the services located on that cluster.
(CVE-2021-3948)

- An out-of-bounds write flaw was found in the UAS (USB Attached SCSI) device emulation of QEMU in versions
prior to 6.2.0-rc0. The device uses the guest supplied stream number unchecked, which can lead to out-of-
bounds access to the UASDevice->data3 and UASDevice->status3 fields. A malicious guest user could use this
flaw to crash QEMU or potentially achieve code execution with the privileges of the QEMU process on the
host. (CVE-2021-3713)

- An off-by-one error was found in the SCSI device emulation in QEMU. It could occur while processing MODE
SELECT commands in mode_sense_page() if the 'page' argument was set to MODE_PAGE_ALLS (0x3f). A malicious
guest could use this flaw to potentially crash QEMU, resulting in a denial of service condition.
(CVE-2021-3930)

- A stack-buffer-overflow was found in QEMU in the NVME component. The flaw lies in nvme_changed_nslist()
where a malicious guest controlling certain input can read out of bounds memory. A malicious user could
use this flaw leading to disclosure of sensitive information. (CVE-2021-3947)
