{"id":"UBUNTU-CVE-2014-0148","details":"Qemu before 2.0 block driver for Hyper-V VHDX Images is vulnerable to infinite loops and other potential issues when calculating BAT entries, due to missing bounds checks for block_size and logical_sector_size variables. These are used to derive other fields like 'sectors_per_block' etc. A user able to alter the Qemu disk image could ise this flaw to crash the Qemu instance resulting in DoS.","modified":"2025-07-16T07:17:12.422011Z","published":"2022-09-29T03:15:00Z","withdrawn":"2025-07-18T16:42:58Z","upstream":["CVE-2014-0148"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2014-0148"},{"type":"REPORT","url":"http://www.openwall.com/lists/oss-security/2014/03/26"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2014-0148"}],"affected":[{"package":{"name":"qemu","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/qemu@2.0.0~rc1+dfsg-0ubuntu3?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.0~rc1+dfsg-0ubuntu3"}]}],"versions":["1.5.0+dfsg-3ubuntu5","1.5.0+dfsg-3ubuntu6","1.6.0+dfsg-2ubuntu1","1.6.0+dfsg-2ubuntu2","1.6.0+dfsg-2ubuntu3","1.6.0+dfsg-2ubuntu4","1.7.0+dfsg-2ubuntu1","1.7.0+dfsg-2ubuntu2","1.7.0+dfsg-2ubuntu3","1.7.0+dfsg-2ubuntu4","1.7.0+dfsg-2ubuntu5","1.7.0+dfsg-2ubuntu7","1.7.0+dfsg-2ubuntu8","1.7.0+dfsg-2ubuntu9","1.7.0+dfsg-3ubuntu1~ppa1","1.7.0+dfsg-3ubuntu1","1.7.0+dfsg-3ubuntu2","1.7.0+dfsg-3ubuntu3","1.7.0+dfsg-3ubuntu4","1.7.0+dfsg-3ubuntu5","1.7.0+dfsg-3ubuntu6","1.7.0+dfsg-3ubuntu7","2.0.0~rc1+dfsg-0ubuntu1","2.0.0~rc1+dfsg-0ubuntu2"],"ecosystem_specific":{"binaries":[{"binary_name":"qemu","binary_version":"2.0.0~rc1+dfsg-0ubuntu3"},{"binary_name":"qemu-common","binary_version":"2.0.0~rc1+dfsg-0ubuntu3"},{"binary_name":"qemu-guest-agent","binary_version":"2.0.0~rc1+dfsg-0ubuntu3"},{"binary_name":"qemu-keymaps","binary_version":"2.0.0~rc1+dfsg-0ubuntu3"},{"binary_name":"qemu-kvm","binary_version":"2.0.0~rc1+dfsg-0ubuntu3"},{"binary_name":"qemu-system","binary_version":"2.0.0~rc1+dfsg-0ubuntu3"},{"binary_name":"qemu-system-aarch64","binary_version":"2.0.0~rc1+dfsg-0ubuntu3"},{"binary_name":"qemu-system-arm","binary_version":"2.0.0~rc1+dfsg-0ubuntu3"},{"binary_name":"qemu-system-common","binary_version":"2.0.0~rc1+dfsg-0ubuntu3"},{"binary_name":"qemu-system-mips","binary_version":"2.0.0~rc1+dfsg-0ubuntu3"},{"binary_name":"qemu-system-misc","binary_version":"2.0.0~rc1+dfsg-0ubuntu3"},{"binary_name":"qemu-system-ppc","binary_version":"2.0.0~rc1+dfsg-0ubuntu3"},{"binary_name":"qemu-system-sparc","binary_version":"2.0.0~rc1+dfsg-0ubuntu3"},{"binary_name":"qemu-system-x86","binary_version":"2.0.0~rc1+dfsg-0ubuntu3"},{"binary_name":"qemu-user","binary_version":"2.0.0~rc1+dfsg-0ubuntu3"},{"binary_name":"qemu-user-static","binary_version":"2.0.0~rc1+dfsg-0ubuntu3"},{"binary_name":"qemu-utils","binary_version":"2.0.0~rc1+dfsg-0ubuntu3"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2014/UBUNTU-CVE-2014-0148.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:H"},{"type":"Ubuntu","score":"medium"}]}
