Alpine: multiple qemu packages: security update to 7.1.0-r4

high Tenable Self-Hosted Container Security Plugin ID 406795

Description

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

 - A DMA reentrancy issue was found in the Tulip device emulation in QEMU. When Tulip reads or writes to the
 rx/tx descriptor or copies the rx/tx frame, it doesn't check whether the destination address is its own
 MMIO address. This can cause the device to trigger MMIO handlers multiple times, possibly leading to a
 stack or heap overflow. A malicious guest could use this flaw to crash the QEMU process on the host,
 resulting in a denial of service condition. (CVE-2022-2962)

 - An integer underflow issue was found in the QEMU VNC server while processing ClientCutText messages in the
 extended format. A malicious client could use this flaw to make QEMU unresponsive by sending a specially
 crafted payload message, resulting in a denial of service. (CVE-2022-3165)
