A double fetch of guest controlled values `cursor->header.width` and `cursor->header.height` can lead to the allocation of a small cursor object followed by a subsequent heap-based buffer overflow. A malicious privileged guest user could use this flaw to crash the QEMU process on the host or potentially execute arbitrary code within the context of the QEMU process.\n\ud83d\udccf Published: 2022-04-29T16:07:33.000Z\n\ud83d\udccf Modified: 2025-03-21T18:03:41.449Z\n\ud83d\udd17 References:\n1. https://bugzilla.redhat.com/show_bug.cgi?id=2036966\n2. https://starlabs.sg/advisories/21-4207/\n3. https://www.debian.org/security/2022/dsa-5133\n4. https://security.gentoo.org/glsa/202208-27\n5. https://lists.debian.org/debian-lts-announce/2022/09/msg00008.html", "creation_timestamp": "2025-03-21T18:19:59.000000Z"}
