{"id":"UBUNTU-CVE-2023-43641","details":"libcue provides an API for parsing and extracting data from CUE sheets. Versions 2.2.1 and prior are vulnerable to out-of-bounds array access. A user of the GNOME desktop environment can be exploited by downloading a cue sheet from a malicious webpage. Because the file is saved to `~/Downloads`, it is then automatically scanned by tracker-miners. And because it has a .cue filename extension, tracker-miners use libcue to parse the file. The file exploits the vulnerability in libcue to gain code execution. This issue is patched in version 2.3.0.","modified":"2026-04-22T16:53:01.147857Z","published":"2023-10-09T17:00:00Z","related":["USN-6423-1","USN-6423-2"],"upstream":["CVE-2023-43641"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-43641"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6423-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6423-2"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-43641"}],"affected":[{"package":{"name":"libcue","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/libcue@1.4.0-1?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.4.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libcue1","binary_version":"1.4.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-43641.json"}},{"package":{"name":"libcue","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/libcue@1.4.0-1?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.4.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libcue1","binary_version":"1.4.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-43641.json"}},{"package":{"name":"libcue","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/libcue@2.2.1-2ubuntu0.1?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.2.1-2ubuntu0.1"}]}],"versions":["2.2.1-2"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"libcue2","binary_version":"2.2.1-2ubuntu0.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-43641.json"}},{"package":{"name":"libcue","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/libcue@2.2.1-3ubuntu0.1?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.2.1-3ubuntu0.1"}]}],"versions":["2.2.1-3build2","2.2.1-3build3"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"libcue2","binary_version":"2.2.1-3ubuntu0.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-43641.json"}},{"package":{"name":"libcue","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/libcue@2.2.1-4ubuntu1?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.2.1-4ubuntu1"}]}],"versions":["2.2.1-4"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"libcue2","binary_version":"2.2.1-4ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-43641.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
