A local attacker could possibly use this issue to read QEMU\nprocess memory. This issue only affected Ubuntu 18.04 LTS and Ubuntu 18.10.\n(CVE-2019-3812)\n\nIt was discovered that QEMU incorrectly handled the Slirp networking\nback-end. An attacker inside the guest could use this issue to cause QEMU\nto crash, resulting in a denial of service, or possibly execute arbitrary\ncode on the host. In the default installation, when QEMU is used with\nlibvirt, attackers would be isolated by the libvirt AppArmor profile.\n(CVE-2019-6778)\n","status":"published","published":"2019-03-27T12:10:22Z","modified":"2026-02-10T04:41:29Z","updated_at":"2026-11-02T16:58:14.019824Z"}]}}
