|---|---|---|---|---|
| CVE-2021-4034 | 7 Canonical, Oracle, Polkit Project and 4 more | 37 Ubuntu Linux, Http Server, Zfs Storage Appliance Kit and 34 more | 2025-11-06 | 7.8 High |
| A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands. An attacker can leverage this by crafting environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully executed the attack can cause a local privilege escalation given unprivileged users administrative rights on the target machine. | ||||

| CVE-2019-17026 | 3 Canonical, Mozilla, Redhat | 5 Ubuntu Linux, Firefox, Thunderbird and 2 more | 2025-11-04 | 8.8 High |
| Incorrect alias information in IonMonkey JIT compiler for setting array elements could lead to a type confusion. We are aware of targeted attacks in the wild abusing this flaw. This vulnerability affects Firefox ESR < 68.4.1, Thunderbird < 68.4.1, and Firefox < 72.0.1. | ||||
| CVE-2021-3737 | 6 Canonical, Fedoraproject, Netapp and 3 more | 18 Ubuntu Linux, Fedora, Hci and 15 more | 2025-11-03 | 7.5 High |
| A flaw was found in python. An improperly handled HTTP response in the HTTP client code of python may allow a remote attacker, who controls the HTTP server, to make the client script enter an infinite loop, consuming CPU time. The highest threat from this vulnerability is to system availability. | ||||
| CVE-2025-5054 | 1 Canonical | 2 Apport, Ubuntu Linux | 2025-11-03 | 4.7 Medium |
| Race condition in Canonical apport up to and including 2.32.0 allows a local attacker to leak sensitive information via PID-reuse by leveraging namespaces. When handling a crash, the function `_check_global_pid_and_forward`, which detects if the crashing process resided in a container, was being called before `consistency_checks`, which attempts to detect if the crashing process had been replaced. Because of this, if a process crashed and was quickly replaced with a containerized one, apport could be made to forward the core dump to the container, potentially leaking sensitive information. `consistency_checks` is now being called before `_check_global_pid_and_forward`. Additionally, given that the PID-reuse race condition cannot be reliably detected from userspace alone, crashes are only forwarded to containers if the kernel provided a pidfd, or if the crashing process was unprivileged (i.e., if dump mode == 1). | ||||
| CVE-2021-25684 | 1 Canonical | 1 Apport | 2025-11-03 | 8.8 High |
| It was discovered that apport in data/apport did not properly open a report file to prevent hanging reads on a FIFO. | ||||
| CVE-2020-15702 | 1 Canonical | 2 Apport, Ubuntu Linux | 2025-11-03 | 7 High |
| TOCTOU Race Condition vulnerability in apport allows a local attacker to escalate privileges and execute arbitrary code. An attacker may exit the crashed process and exploit PID recycling to spawn a root process with the same PID as the crashed process, which can then be used to escalate privileges. Fixed in 2.20.1-0ubuntu2.24, 2.20.9 versions prior to 2.20.9-0ubuntu7.16 and 2.20.11 versions prior to 2.20.11-0ubuntu27.6. Was ZDI-CAN-11234. | ||||
| CVE-2020-12762 | 6 Canonical, Debian, Fedoraproject and 3 more | 7 Ubuntu Linux, Debian Linux, Fedora and 4 more | 2025-11-03 | 7.8 High |
| json-c through 0.14 has an integer overflow and out-of-bounds write via a large JSON file, as demonstrated by printbuf_memappend. | ||||
| CVE-2019-15790 | 2 Apport Project, Canonical | 2 Apport, Ubuntu Linux | 2025-11-03 | 2.8 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-2019-11483 | 2 Apport Project, Canonical | 2 Apport, Ubuntu Linux | 2025-11-03 | 7 High |
| 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-2017-14180 | 2 Apport Project, Canonical | 2 Apport, Ubuntu Linux | 2025-11-03 | N/A |
| 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-2015-1325 | 1 Canonical | 1 Ubuntu Linux | 2025-11-03 | N/A |
| Race condition in Apport before 2.17.2-0ubuntu1.1 as packaged in Ubuntu 15.04, before 2.14.70ubuntu8.5 as packaged in Ubuntu 14.10, before 2.14.1-0ubuntu3.11 as packaged in Ubuntu 14.04 LTS, and before 2.0.1-0ubuntu17.9 as packaged in Ubuntu 12.04 LTS allow local users to write to arbitrary files and gain root privileges. | ||||
| CVE-2019-11043 | 6 Canonical, Debian, Fedoraproject and 3 more | 26 Ubuntu Linux, Debian Linux, Fedora and 23 more | 2025-11-03 | 8.7 High |
