| CVE-2020-8831 | 2 Apport Project, Canonical | 2 Apport, Ubuntu Linux | 2020-06-24 | 2.1 LOW | 5.5 MEDIUM |
| 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. | |||||
| CVE-2020-8833 | 2 Apport Project, Canonical | 2 Apport, Ubuntu Linux | 2020-06-24 | 1.9 LOW | 4.7 MEDIUM |
| 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. | |||||
| CVE-2019-11482 | 2 Apport Project, Canonical | 2 Apport, Ubuntu Linux | 2020-02-12 | 1.9 LOW | 4.7 MEDIUM |
| Sander Bos discovered a time of check to time of use (TOCTTOU) vulnerability in apport that allowed a user to cause core files to be written in arbitrary directories. | |||||
| CVE-2016-9951 | 1 Apport Project | 1 Apport | 2017-01-07 | 4.3 MEDIUM | 6.5 MEDIUM |
| An issue was discovered in Apport before 2.20.4. A malicious Apport crash file can contain a restart command in `RespawnCommand` or `ProcCmdline` fields. This command will be executed if a user clicks the Relaunch button on the Apport prompt from the malicious crash file. The fix is to only show the Relaunch button on Apport crash files generated by local systems. The Relaunch button will be hidden when crash files are opened directly in Apport-GTK. | |||||
