{"id":"UBUNTU-CVE-2023-1326","details":"A privilege escalation attack was found in apport-cli 2.26.0 and earlier which is similar to CVE-2023-26604. If a system is specially configured to allow unprivileged users to run sudo apport-cli, less is configured as the pager, and the terminal size can be set: a local attacker can escalate privilege. It is extremely unlikely that a system administrator would configure sudo to allow unprivileged users to perform this class of exploit.","modified":"2026-02-04T04:16:33.427371Z","published":"2023-04-13T12:33:00Z","related":["USN-6018-1"],"upstream":["CVE-2023-1326"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-1326"},{"type":"REPORT","url":"https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-26604"},{"type":"REPORT","url":"https://github.com/systemd/systemd/issues/5666"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6018-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-1326"}],"affected":[{"package":{"name":"apport","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/apport@2.20.9-0ubuntu7.29?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.20.9-0ubuntu7.29"}]}],"versions":["2.20.7-0ubuntu3","2.20.7-0ubuntu3.1","2.20.7-0ubuntu4","2.20.8-0ubuntu1","2.20.8-0ubuntu2","2.20.8-0ubuntu3","2.20.8-0ubuntu4","2.20.8-0ubuntu5","2.20.8-0ubuntu6","2.20.8-0ubuntu7","2.20.8-0ubuntu8","2.20.8-0ubuntu9","2.20.8-0ubuntu10","2.20.9-0ubuntu1","2.20.9-0ubuntu2","2.20.9-0ubuntu4","2.20.9-0ubuntu5","2.20.9-0ubuntu6","2.20.9-0ubuntu7","2.20.9-0ubuntu7.1","2.20.9-0ubuntu7.2","2.20.9-0ubuntu7.3","2.20.9-0ubuntu7.4","2.20.9-0ubuntu7.5","2.20.9-0ubuntu7.6","2.20.9-0ubuntu7.7","2.20.9-0ubuntu7.8","2.20.9-0ubuntu7.9","2.20.9-0ubuntu7.11","2.20.9-0ubuntu7.12","2.20.9-0ubuntu7.13","2.20.9-0ubuntu7.14","2.20.9-0ubuntu7.15","2.20.9-0ubuntu7.16","2.20.9-0ubuntu7.17","2.20.9-0ubuntu7.18","2.20.9-0ubuntu7.19","2.20.9-0ubuntu7.20","2.20.9-0ubuntu7.21","2.20.9-0ubuntu7.23","2.20.9-0ubuntu7.24","2.20.9-0ubuntu7.26","2.20.9-0ubuntu7.27","2.20.9-0ubuntu7.28"],"ecosystem_specific":{"availability":"No
