{"id":"UBUNTU-CVE-2020-11869","details":"An integer overflow was found in QEMU 4.0.1 through 4.2.0 in the way it implemented ATI VGA emulation. This flaw occurs in the ati_2d_blt() routine in hw/display/ati-2d.c while handling MMIO write operations through the ati_mm_write() callback. A malicious guest could abuse this flaw to crash the QEMU process, resulting in a denial of service.","modified":"2026-01-30T00:39:00.245351Z","published":"2020-04-27T19:15:00Z","related":["USN-4372-1"],"upstream":["CVE-2020-11869"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2020-11869"},{"type":"REPORT","url":"https://www.openwall.com/lists/oss-security/2020/04/24/2"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-4372-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2020-11869"}],"affected":[{"package":{"name":"qemu","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/qemu@1:4.2-3ubuntu6.1?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:4.2-3ubuntu6.1"}]}],"versions":["1:4.0+dfsg-0ubuntu9","1:4.0+dfsg-0ubuntu10","1:4.2-1ubuntu1","1:4.2-1ubuntu2","1:4.2-3ubuntu1","1:4.2-3ubuntu2","1:4.2-3ubuntu3","1:4.2-3ubuntu4","1:4.2-3ubuntu5","1:4.2-3ubuntu6"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"qemu","binary_version":"1:4.2-3ubuntu6.1"},{"binary_name":"qemu-block-extra","binary_version":"1:4.2-3ubuntu6.1"},{"binary_name":"qemu-guest-agent","binary_version":"1:4.2-3ubuntu6.1"},{"binary_name":"qemu-kvm","binary_version":"1:4.2-3ubuntu6.1"},{"binary_name":"qemu-system","binary_version":"1:4.2-3ubuntu6.1"},{"binary_name":"qemu-system-arm","binary_version":"1:4.2-3ubuntu6.1"},{"binary_name":"qemu-system-common","binary_version":"1:4.2-3ubuntu6.1"},{"binary_name":"qemu-system-data","binary_version":"1:4.2-3ubuntu6.1"},{"binary_name":"qemu-system-gui","binary_version":"1:4.2-3ubuntu6.1"},{"binary_name":"qemu-system-mips","binary_version":"1:4.2-3ubuntu6.1"},{"binary_name":"qemu-system-misc","binary_version":"1:4.2-3ubuntu6.1"},{"binary_name":"qemu-system-ppc","binary_version":"1:4.2-3ubuntu6.1"},{"binary_name":"qemu-system-s390x","binary_version":"1:4.2-3ubuntu6.1"},{"binary_name":"qemu-system-sparc","binary_version":"1:4.2-3ubuntu6.1"},{"binary_name":"qemu-system-x86","binary_version":"1:4.2-3ubuntu6.1"},{"binary_name":"qemu-system-x86-microvm","binary_version":"1:4.2-3ubuntu6.1"},{"binary_name":"qemu-system-x86-xen","binary_version":"1:4.2-3ubuntu6.1"},{"binary_name":"qemu-user","binary_version":"1:4.2-3ubuntu6.1"},{"binary_name":"qemu-user-binfmt","binary_version":"1:4.2-3ubuntu6.1"},{"binary_name":"qemu-user-static","binary_version":"1:4.2-3ubuntu6.1"},{"binary_name":"qemu-utils","binary_version":"1:4.2-3ubuntu6.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-11869.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L"},{"type":"Ubuntu","score":"medium"}]}
