Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm packages provide the user-space component for running virtual machines that use KVM.

The following packages have been upgraded to a later upstream version: qemu-kvm (7.2.0). (BZ#2111769, BZ#2135806)

Security Fix(es):

* QEMU: VNC: integer underflow in vnc_client_cut_text_ext leads to CPU exhaustion (CVE-2022-3165) * QEMU: ACPI ERST: memory corruption issues in read_erst_record and write_erst_record (CVE-2022-4172)

Affected: Alpaquita:23: qemu

An integer overflow and buffer overflow issues were found in the ACPI Error Record Serialization Table (ERST) device of QEMU in the read_erst_record() and write_erst_record() functions. Both issues may allow the guest to overrun the host buffer allocated for the ERST memory device. A malicious guest could use these flaws to crash the QEMU process on the host.
