{"id":"CVE-2019-15790","details":"Apport reads and writes information on a crashed process to /proc/pid with elevated privileges. Apport then determines which user the crashed process belongs to by reading /proc/pid through get_pid_info() in data/apport. An unprivileged user could exploit this to read information about a privileged running process by exploiting PID recycling. This information could then be used to obtain ASLR offsets for a process with an existing memory corruption vulnerability. The initial fix introduced regressions in the Python Apport library due to a missing argument in Report.add_proc_environ in apport/report.py. It also caused an autopkgtest failure when reading /proc/pid and with Python 2 compatibility by reading /proc maps. The initial and subsequent regression fixes are in 2.20.11-0ubuntu16, 2.20.11-0ubuntu8.6, 2.20.9-0ubuntu7.12, 2.20.1-0ubuntu2.22 and 2.14.1-0ubuntu3.29+esm3.","modified":"2026-03-15T22:30:45.889934Z","published":"2020-04-28T00:15:12.913Z","references":[{"type":"WEB","url":"http://seclists.org/fulldisclosure/2025/Jun/9"},{"type":"WEB","url":"http://packetstormsecurity.com/files/172858/Ubuntu-Apport-Whoopsie-DoS-Integer-Overflow.html"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/4171-1/"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/4171-3/"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/4171-4/"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/4171-5/"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/4171-2/"},{"type":"REPORT","url":"https://bugs.launchpad.net/apport/+bug/1854237"},{"type":"REPORT","url":"https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1839795"},{"type":"REPORT","url":"https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1851806"},{"type":"FIX","url":"https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1850929"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"14.04"}]},{"events":[{"introduced":"0"},{"last_affected":"16.04"}]},{"events":[{"introduced":"0"},{"last_affected":"18.04"}]},{"events":[{"introduced":"0"},{"last_affected":"19.04"}]},{"events":[{"introduced":"0"},{"last_affected":"19.10"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2019-15790.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}
