CVSS: 5.6EPSS: 0%CPEs: 5EXPL: 1CVE-2020-8833 – Apport race condition in crash report permissions
https://notcve.org/view.php?id=CVE-2020-8833
Time-of-check Time-of-use Race Condition vulnerability on crash report ownership change in Apport allows for a possible privilege escalation opportunity. If fs.protected_symlinks is disabled, this can be exploited between the os.open and os.chown calls when the Apport cron script clears out crash files of size 0. A symlink with the same name as the deleted file can then be created upon which chown will be called, changing the file owner to root. Fixed in versions 2.20.1-0ubuntu2.23, 2.20.9-0ubuntu7.14, 2.20.11-0ubuntu8.8 and 2.20.11-0ubuntu22. Una vulnerabilidad de Condición de Carrera de tipo Time-of-check Time-of-use en el cambio de propiedad del reporte de bloqueo en Apport, permite una posible oportunidad de escalada de privilegios. • https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1862933 https://usn.ubuntu.com/4315-1 https://usn.ubuntu.com/4315-2 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
CVSS: 6.5EPSS: 0%CPEs: 5EXPL: 1CVE-2020-8831 – World writable root owned lock file created in user controllable location
https://notcve.org/view.php?id=CVE-2020-8831
Apport creates a world writable lock file with root ownership in the world writable /var/lock/apport directory. If the apport/ directory does not exist (this is not uncommon as /var/lock is a tmpfs), it will create the directory, otherwise it will simply continue execution using the existing directory. This allows for a symlink attack if an attacker were to create a symlink at /var/lock/apport, changing apport's lock file location. This file could then be used to escalate privileges, for example. Fixed in versions 2.20.1-0ubuntu2.23, 2.20.9-0ubuntu7.14, 2.20.11-0ubuntu8.8 and 2.20.11-0ubuntu22. • https://launchpad.net/bugs/1862348 https://usn.ubuntu.com/4315-1 https://usn.ubuntu.com/4315-2 • CWE-59: Improper Link Resolution Before File Access ('Link Following') CWE-379: Creation of Temporary File in Directory with Insecure Permissions •
CVSS: 3.3EPSS: 0%CPEs: 6EXPL: 3CVE-2019-15790 – Apport reads PID files with elevated privileges
https://notcve.org/view.php?id=CVE-2019-15790
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. • http://packetstormsecurity.com/files/172858/Ubuntu-Apport-Whoopsie-DoS-Integer-Overflow.html https://bugs.launchpad.net/apport/+bug/1854237 https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1839795 https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1850929 https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1851806 https://usn.ubuntu.com/4171-1 https://usn.ubuntu.com/4171-2 https://usn.ubuntu.com/4171-3 https://usn.ubuntu.com/4171-4 https://usn.u • CWE-250: Execution with Unnecessary Privileges CWE-269: Improper Privilege Management •

Sander Bos discovered Apport mishandled crash dumps originating from containers. This could be used by a local attacker to generate a crash report for a privileged process that is readable by an unprivileged user. Sander Bos detectó que Apport manejó inapropiadamente los vertederos accidentales procedentes de contenedores. Esto podría ser utilizado por un atacante local para generar un reporte de bloqueo para un proceso privilegiado que pueda ser leído por un usuario no privilegiado. • https://usn.ubuntu.com/usn/usn-4171-1 https://usn.ubuntu.com/usn/usn-4171-2 •
