Azure Linux 3.0 Security Update: qemu / qemu-kvm (CVE-2022-2962)

high Nessus Plugin ID 215403

Synopsis

The remote Azure Linux host is missing one or more security updates.

Description

The version of qemu / qemu-kvm installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2022-2962 advisory.

 - 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)

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

Solution

Update the affected packages.
