| CVE-2018-12397 | 4 Canonical, Debian, Mozilla and 1 more | 8 Ubuntu Linux, Debian Linux, Firefox and 5 more | 2025-11-25 | N/A |
| A WebExtension can request access to local files without the warning prompt stating that the extension will "Access your data for all websites" being displayed to the user. This allows extensions to run content scripts in local pages without permission warnings when a local file is opened. This vulnerability affects Firefox ESR < 60.3 and Firefox < 63. | ||||
| CVE-2022-0543 | 3 Canonical, Debian, Redis | 3 Ubuntu Linux, Debian Linux, Redis | 2025-11-10 | 10.0 Critical |
| It was discovered, that redis, a persistent key-value database, due to a packaging issue, is prone to a (Debian-specific) Lua sandbox escape, which could result in remote code execution. | ||||
| CVE-2020-7247 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2025-11-07 | 9.8 Critical |
| smtp_mailaddr in smtp_session.c in OpenSMTPD 6.6, as used in OpenBSD 6.6 and other products, allows remote attackers to execute arbitrary commands as root via a crafted SMTP session, as demonstrated by shell metacharacters in a MAIL FROM field. This affects the "uncommented" default configuration. The issue exists because of an incorrect return value upon failure of input validation. | ||||
| CVE-2019-16928 | 4 Canonical, Debian, Exim and 1 more | 4 Ubuntu Linux, Debian Linux, Exim and 1 more | 2025-11-07 | 9.8 Critical |
| Exim 4.92 through 4.92.2 allows remote code execution, a different vulnerability than CVE-2019-15846. There is a heap-based buffer overflow in string_vformat in string.c involving a long EHLO command. | ||||
| CVE-2020-11651 | 5 Canonical, Debian, Opensuse and 2 more | 5 Ubuntu Linux, Debian Linux, Leap and 2 more | 2025-11-07 | 9.8 Critical |
| An issue was discovered in SaltStack Salt before 2019.2.4 and 3000 before 3000.2. The salt-master process ClearFuncs class does not properly validate method calls. This allows a remote user to access some methods without authentication. These methods can be used to retrieve user tokens from the salt master and/or run arbitrary commands on salt minions. | ||||
| CVE-2020-11652 | 6 Blackberry, Canonical, Debian and 3 more | 6 Workspaces Server, Ubuntu Linux, Debian Linux and 3 more | 2025-11-07 | 6.5 Medium |
| An issue was discovered in SaltStack Salt before 2019.2.4 and 3000 before 3000.2. The salt-master process ClearFuncs class allows access to some methods that improperly sanitize paths. These methods allow arbitrary directory access to authenticated users. | ||||
| CVE-2018-6789 | 3 Canonical, Debian, Exim | 3 Ubuntu Linux, Debian Linux, Exim | 2025-11-07 | 9.8 Critical |
| An issue was discovered in the base64d function in the SMTP listener in Exim before 4.90.1. By sending a handcrafted message, a buffer overflow may happen. This can be used to execute code remotely. | ||||
| CVE-2023-3567 | 3 Canonical, Linux, Redhat | 5 Ubuntu Linux, Linux Kernel, Enterprise Linux and 2 more | 2025-11-06 | 7.1 High |
| A use-after-free flaw was found in vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux Kernel. This issue may allow an attacker with local user access to cause a system crash or leak internal kernel information. | ||||
| CVE-2019-13272 | 6 Canonical, Debian, Fedoraproject and 3 more | 25 Ubuntu Linux, Debian Linux, Fedora and 22 more | 2025-11-06 | 7.8 High |
| In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the credentials of a process that wants to create a ptrace relationship, which allows local users to obtain root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops privileges and calls execve (potentially allowing control by an attacker). One contributing factor is an object lifetime issue (which can also cause a panic). Another contributing factor is incorrect marking of a ptrace relationship as privileged, which is exploitable through (for example) Polkit's pkexec helper with PTRACE_TRACEME. NOTE: SELinux deny_ptrace might be a usable workaround in some environments. | ||||
| CVE-2021-3560 | 4 Canonical, Debian, Polkit Project and 1 more | 10 Ubuntu Linux, Debian Linux, Polkit and 7 more | 2025-11-06 | 7.8 High |
| It was found that polkit could be tricked into bypassing the credential checks for D-Bus requests, elevating the privileges of the requestor to the root user. This flaw could be used by an unprivileged local attacker to, for example, create a new local administrator. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
| 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. | ||||
