CVE-2020-8831 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2023-12-10 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-2019-15790 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2023-12-10 2.1 LOW 3.3 LOW
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.
CVE-2020-8833 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2023-12-10 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-2019-11481 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2023-12-10 6.1 MEDIUM 7.8 HIGH
Kevin Backhouse discovered that apport would read a user-supplied configuration file with elevated privileges. By replacing the file with a symbolic link, a user could get apport to read any file on the system as root, with unknown consequences.
CVE-2019-11483 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2023-12-10 2.1 LOW 3.3 LOW
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.
CVE-2019-11482 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2023-12-10 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-2019-11485 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2023-12-10 2.1 LOW 3.3 LOW
Sander Bos discovered Apport's lock file was in a world-writable directory which allowed all users to prevent crash handling.
CVE-2019-7307 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2023-12-10 4.4 MEDIUM 7.0 HIGH
Apport before versions 2.14.1-0ubuntu3.29+esm1, 2.20.1-0ubuntu2.19, 2.20.9-0ubuntu7.7, 2.20.10-0ubuntu27.1, 2.20.11-0ubuntu5 contained a TOCTTOU vulnerability when reading the users ~/.apport-ignore.xml file, which allows a local attacker to replace this file with a symlink to any other file on the system and so cause Apport to include the contents of this other file in the resulting crash report. The crash report could then be read by that user either by causing it to be uploaded and reported to Launchpad, or by leveraging some other vulnerability to read the resulting crash report, and so allow the user to read arbitrary files on the system.
CVE-2017-14177 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2023-12-10 7.2 HIGH 7.8 HIGH
Apport through 2.20.7 does not properly handle core dumps from setuid binaries allowing local users to create certain files as root which an attacker could leverage to perform a denial of service via resource exhaustion or possibly gain root privileges. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-1324.
CVE-2017-14180 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2023-12-10 7.2 HIGH 7.8 HIGH
Apport 2.13 through 2.20.7 does not properly handle crashes originating from a PID namespace allowing local users to create certain files as root which an attacker could leverage to perform a denial of service via resource exhaustion or possibly gain root privileges, a different vulnerability than CVE-2017-14179.
CVE-2017-14179 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2023-12-10 7.2 HIGH 7.8 HIGH
Apport before 2.13 does not properly handle crashes originating from a PID namespace allowing local users to create certain files as root which an attacker could leverage to perform a denial of service via resource exhaustion, possibly gain root privileges, or escape from containers.
CVE-2018-6552 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2023-12-10 7.2 HIGH 7.8 HIGH
Apport does not properly handle crashes originating from a PID namespace allowing local users to create certain files as root which an attacker could leverage to perform a denial of service via resource exhaustion, possibly gain root privileges, or escape from containers. The is_same_ns() function returns True when /proc/<global pid>/ does not exist in order to indicate that the crash should be handled in the global namespace rather than inside of a container. However, the portion of the data/apport code that decides whether or not to forward a crash to a container does not always replace sys.argv[1] with the value stored in the host_pid variable when /proc/<global pid>/ does not exist which results in the container pid being used in the global namespace. This flaw affects versions 2.20.8-0ubuntu4 through 2.20.9-0ubuntu7, 2.20.7-0ubuntu3.7, 2.20.7-0ubuntu3.8, 2.20.1-0ubuntu2.15 through 2.20.1-0ubuntu2.17, and 2.14.1-0ubuntu3.28.
CVE-2017-10708 1 Apport Project 1 Apport 2023-12-10 6.8 MEDIUM 7.8 HIGH
An issue was discovered in Apport through 2.20.x. In apport/report.py, Apport sets the ExecutablePath field and it then uses the path to run package specific hooks without protecting against path traversal. This allows remote attackers to execute arbitrary code via a crafted .crash file.
CVE-2016-9949 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2023-12-10 9.3 HIGH 7.8 HIGH
An issue was discovered in Apport before 2.20.4. In apport/ui.py, Apport reads the CrashDB field and it then evaluates the field as Python code if it begins with a "{". This allows remote attackers to execute arbitrary Python code.
