A vulnerability was found in Apport on Ubuntu. It has been rated as problematic. This issue affects the function get_pid_info
of the file /proc/pid. The manipulation with an unknown input leads to a unnecessary privileges vulnerability. Using CWE to declare the problem leads to CWE-250. The product performs an operation at a privilege level that is higher than the minimum level required, which creates new weaknesses or amplifies the consequences of other weaknesses. Impacted is confidentiality. The summary by CVE is:
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.
The weakness was released 04/28/2020 (Website). The advisory is shared at bugs.launchpad.net. The identification of this vulnerability is CVE-2019-15790 since 08/29/2019. An attack has to be approached locally. The successful exploitation needs a simple authentication. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1068 for this issue.
Upgrading to version 2.20.11-0ubuntu16, 2.20.11-0ubuntu8.6, 2.20.9-0ubuntu7.12, 2.20.1-0ubuntu2.22 or 2.14.1-0ubuntu3.29+esm3 eliminates this vulnerability.
