{"id":"UBUNTU-CVE-2021-37600","details":"An integer overflow in util-linux through 2.37.1 can potentially cause a buffer overflow if an attacker were able to use system resources in a way that leads to a large number in the /proc/sysvipc/sem file. NOTE: this is unexploitable in GNU C Library environments, and possibly in all realistic environments.","modified":"2026-04-22T14:52:29.604608Z","published":"2021-07-30T14:15:00Z","upstream":["CVE-2021-37600"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2021-37600"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2021-37600"}],"affected":[{"package":{"name":"util-linux","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/util-linux@2.37.2-4ubuntu2?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.37.2-4ubuntu2"}]}],"versions":["2.36.1-8ubuntu1","2.37.2-4ubuntu1"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_version":"2.37.2-4ubuntu2","binary_name":"bsdextrautils"},{"binary_name":"bsdutils","binary_version":"1:2.37.2-4ubuntu2"},{"binary_name":"eject","binary_version":"2.37.2-4ubuntu2"},{"binary_name":"fdisk","binary_version":"2.37.2-4ubuntu2"},{"binary_name":"libblkid1","binary_version":"2.37.2-4ubuntu2"},{"binary_name":"libfdisk1","binary_version":"2.37.2-4ubuntu2"},{"binary_name":"libmount1","binary_version":"2.37.2-4ubuntu2"},{"binary_name":"libsmartcols1","binary_version":"2.37.2-4ubuntu2"},{"binary_name":"libuuid1","binary_version":"2.37.2-4ubuntu2"},{"binary_name":"mount","binary_version":"2.37.2-4ubuntu2"},{"binary_name":"rfkill","binary_version":"2.37.2-4ubuntu2"},{"binary_version":"2.37.2-4ubuntu2","binary_name":"util-linux"},{"binary_name":"util-linux-locales","binary_version":"2.37.2-4ubuntu2"},{"binary_name":"uuid-runtime","binary_version":"2.37.2-4ubuntu2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2021/UBUNTU-CVE-2021-37600.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"low"}]}
