Red Hat Security Advisory: Advanced Virtualization 8.2.1z security update
A vulnerability in the QEMU disk image utility (qemu-img) 'info' command allows a specially crafted image file containing a json:{} value describing block devices in QMP to cause excessive memory or CPU consumption. This can lead to denial of service or unintended read/write access to an existing external file on the host running the process. The issue affects the Advanced Virtualization module used in Red Hat environments with KVM. No CVSS score is provided, but the severity is assessed as high.
AI Analysis
Technical Summary
CVE-2024-4467 describes a flaw in the qemu-img 'info' command where processing a specially crafted disk image file with a json:{} block device description can cause the qemu-img process to consume excessive memory or CPU resources. This may result in denial of service or unauthorized read/write operations on external files. This vulnerability affects the Advanced Virtualization module in Red Hat products that manage KVM virtual machines. The advisory does not specify affected versions or provide a CVSS score.
Potential Impact
The vulnerability can cause denial of service by exhausting host memory or CPU resources when processing malicious disk image files. Additionally, it may allow unintended read or write access to existing external files on the host, potentially leading to data corruption or exposure. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the Red Hat advisory RHSA-2024:4727 for current remediation guidance. Until an official fix is available, avoid processing untrusted or suspicious disk image files with qemu-img 'info'.
