{"id":"UBUNTU-CVE-2022-4055","details":"When xdg-mail is configured to use thunderbird for mailto URLs, improper parsing of the URL can lead to additional headers being passed to thunderbird that should not be included per RFC 2368. An attacker can use this method to create a mailto URL that looks safe to users, but will actually attach files when clicked.","modified":"2026-04-27T17:48:40.225708Z","published":"2022-11-19T00:15:00Z","upstream":["CVE-2022-4055"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-4055"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2022-4055"}],"affected":[{"package":{"name":"xdg-utils","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/xdg-utils@1.1.1-1ubuntu1.16.04.5?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.0~rc3+git20150907-1ubuntu2","1.1.0~rc3+git20150907-1ubuntu3","1.1.1-1ubuntu1","1.1.1-1ubuntu1.16.04.1","1.1.1-1ubuntu1.16.04.3","1.1.1-1ubuntu1.16.04.4","1.1.1-1ubuntu1.16.04.5"],"ecosystem_specific":{"binaries":[{"binary_version":"1.1.1-1ubuntu1.16.04.5","binary_name":"xdg-utils"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-4055.json"}},{"package":{"name":"xdg-utils","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/xdg-utils@1.1.2-1ubuntu2.5?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.1-1ubuntu2","1.1.1-1ubuntu3","1.1.2-1ubuntu1","1.1.2-1ubuntu2","1.1.2-1ubuntu2.2","1.1.2-1ubuntu2.3","1.1.2-1ubuntu2.4","1.1.2-1ubuntu2.5"],"ecosystem_specific":{"binaries":[{"binary_version":"1.1.2-1ubuntu2.5","binary_name":"xdg-utils"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-4055.json"}},{"package":{"name":"xdg-utils","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/xdg-utils@1.1.3-2ubuntu1.20.04.2?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.3-1ubuntu2","1.1.3-2ubuntu1","1.1.3-2ubuntu1.20.04.1","1.1.3-2ubuntu1.20.04.2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.1.3-2ubuntu1.20.04.2","binary_name":"xdg-utils"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-4055.json"}},{"package":{"name":"xdg-utils","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/xdg-utils@1.1.3-4.1ubuntu3~22.04.1?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.3-2ubuntu2","1.1.3-4.1ubuntu1","1.1.3-4.1ubuntu1.22.04.1","1.1.3-4.1ubuntu3~22.04.1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.1.3-4.1ubuntu3~22.04.1","binary_name":"xdg-utils"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-4055.json"}},{"package":{"name":"xdg-utils","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/xdg-utils@1.1.3-4.1ubuntu3?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.3-4.1ubuntu3"],"ecosystem_specific":{"binaries":[{"binary_version":"1.1.3-4.1ubuntu3","binary_name":"xdg-utils"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-4055.json"}},{"package":{"name":"xdg-utils","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/xdg-utils@1.2.1-2ubuntu1?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.1-2ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.2.1-2ubuntu1","binary_name":"xdg-utils"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-4055.json"}},{"package":{"name":"xdg-utils","ecosystem":"Ubuntu:26.04","purl":"pkg:deb/ubuntu/xdg-utils@1.2.1-2ubuntu2?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.1-2ubuntu1","1.2.1-2ubuntu2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.2.1-2ubuntu2","binary_name":"xdg-utils"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-4055.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:H/A:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:H/A:N"},{"type":"Ubuntu","score":"low"}]}
