| CVE | Summary | Source | Max CVSS | EPSS % | Published | Updated |
|---|---|---|---|---|---|---|
| CVE-2026-35535 | In Sudo through 1.9.17p2 before 3e474c2, a failure of a setuid, setgid, or setgroups call, during a privilege drop before running the mailer, is not a fatal error and can lead to privilege escalation. | [email protected] | 7.4 | 0.00% | 2026-04-03 | 2026-06-02 |
| CVE-2025-32463 KEV | Sudo before 1.9.17p1 allows local users to obtain root access because /etc/nsswitch.conf from a user-controlled directory is used with the --chroot option. | [email protected] | 9.3 | 57.34% | 2025-06-30 | 2025-11-05 |
| CVE-2025-32462 | Sudo before 1.9.17p1, when used with a sudoers file that specifies a host that is neither the current host nor ALL, allows listed users to execute commands on unintended machines. | [email protected] | 2.8 | 30.01% | 2025-06-30 | 2025-11-03 |
| CVE-2023-7090 | A flaw was found in sudo in the handling of ipa_hostname, where ipa_hostname from /etc/sssd/sssd.conf was not propagated in sudo. Therefore, it leads to privilege mismanagement vulnerability in applications, where client hosts retain privileges even after retracting them. | [email protected] | 6.6 | 0.08% | 2023-12-23 | 2024-11-21 |
| CVE-2023-42465 | Sudo before 1.9.15 might allow row hammer attacks (for authentication bypass or privilege escalation) because application logic sometimes is based on not equaling an error value (instead of equaling a success value), and because the values do not resist flips of a single bit. | [email protected] | 7.0 | 0.00% | 2023-12-22 | 2025-11-04 |
| CVE-2023-28487 | Sudo before 1.9.13 does not escape control characters in sudoreplay output. | [email protected] | 5.3 | 0.10% | 2023-03-16 | 2024-11-21 |
| CVE-2023-28486 | Sudo before 1.9.13 does not escape control characters in log messages. | [email protected] | 5.3 | 0.10% | 2023-03-16 | 2024-11-21 |
| CVE-2023-27320 | Sudo before 1.9.13p2 has a double free in the per-command chroot feature. | [email protected] | 7.2 | 0.17% | 2023-02-28 | 2025-03-21 |
| CVE-2023-22809 | In Sudo before 1.9.12p2, the sudoedit (aka -e) feature mishandles extra arguments passed in the user-provided environment variables (SUDO_EDITOR, VISUAL, and EDITOR), allowing a local attacker to append arbitrary entries to the list of files to process. This can lead to privilege escalation. Affected versions are 1.8.0 through 1.9.12.p1. The problem exists because a user-specified editor may contain a "--" argument that defeats a protection mechanism, e.g., an EDITOR='vim -- /path/to/extra/file' | [email protected] | 7.8 | 41.68% | 2023-01-18 | 2025-04-04 |
| CVE-2022-43995 | Sudo 1.8.0 through 1.9.12, with the crypt() password backend, contains a plugins/sudoers/auth/passwd.c array-out-of-bounds error that can result in a heap-based buffer over-read. This can be triggered by arbitrary local users with access to Sudo by entering a password of seven characters or fewer. The impact could vary depending on the system libraries, compiler, and processor architecture. | [email protected] | 7.1 | 0.06% | 2022-11-02 | 2025-05-05 |
| CVE-2021-3156 KEV | Sudo before 1.9.5p2 contains an off-by-one error that can result in a heap-based buffer overflow, which allows privilege escalation to root via "sudoedit -s" and a command-line argument that ends with a single backslash character. | [email protected] | 7.8 | 92.55% | 2021-01-26 | 2025-11-10 |
| CVE-2021-23240 | selinux_edit_copy_tfiles in sudoedit in Sudo before 1.9.5 allows a local unprivileged user to gain file ownership and escalate privileges by replacing a temporary file with a symlink to an arbitrary file target. This affects SELinux RBAC support in permissive mode. Machines without SELinux are not vulnerable. | [email protected] | 7.8 | 0.22% | 2021-01-12 | 2024-11-21 |
| CVE-2021-23239 | The sudoedit personality of Sudo before 1.9.5 may allow a local unprivileged user to perform arbitrary directory-existence tests by winning a sudo_edit.c race condition in replacing a user-controlled directory by a symlink to an arbitrary path. | [email protected] | 2.5 | 0.10% | 2021-01-12 | 2024-11-21 |
| CVE-2019-18634 | In Sudo before 1.8.26, if pwfeedback is enabled in /etc/sudoers, users can trigger a stack-based buffer overflow in the privileged sudo process. (pwfeedback is a default setting in Linux Mint and elementary OS; however, it is NOT the default for upstream and many other packages, and would exist only if enabled by an administrator.) The attacker needs to deliver a long string to the stdin of getln() in tgetpass.c. | [email protected] | 7.8 | 88.01% | 2020-01-29 | 2024-11-21 |
| CVE-2005-4890 | There is a possible tty hijacking in shadow 4.x before 4.1.5 and sudo 1.x before 1.7.4 via "su - user -c program". The user session can be escaped to the parent session by using the TIOCSTI ioctl to push characters into the input buffer to be read by the next process. | [email protected] | 7.8 | 0.14% | 2019-11-04 | 2024-11-21 |
| CVE-2019-18684 | Sudo through 1.8.29 allows local users to escalate to root if they have write access to file descriptor 3 of the sudo process. This occurs because of a race condition between determining a uid, and the setresuid and openat system calls. The attacker can write "ALL ALL=(ALL) NOPASSWD:ALL" to /proc/#####/fd/3 at a time when Sudo is prompting for a password. NOTE: This has been disputed due to the way Linux /proc works. It has been argued that writing to /proc/#####/fd/3 would only be viable if you | [email protected] | 7.0 | 0.10% | 2019-11-04 | 2024-11-21 |
| CVE-2019-14287 | In Sudo before 1.8.28, an attacker with access to a Runas ALL sudoer account can bypass certain policy blacklists and session PAM modules, and can cause incorrect logging, by invoking sudo with a crafted user ID. For example, this allows bypass of !root configuration, and USER= logging, for a "sudo -u \#$((0xffffffff))" command. | [email protected] | 8.8 | 85.81% | 2019-10-17 | 2024-11-21 |
| CVE-2016-7076 | sudo before version 1.8.18p1 is vulnerable to a bypass in the sudo noexec restriction if application run via sudo executed wordexp() C library function with a user supplied argument. A local user permitted to run such application via sudo with noexec restriction could possibly use this flaw to execute arbitrary commands with elevated privileges. | [email protected] | 6.4 | 0.07% | 2018-05-29 | 2024-11-21 |
| CVE-2015-8239 | The SHA-2 digest support in the sudoers plugin in sudo after 1.8.7 allows local users with write permissions to parts of the called command to replace them before it is executed. | [email protected] | 7.0 | 0.88% | 2017-10-10 | 2026-05-13 |
| CVE-2017-1000368 | Todd Miller's sudo version 1.8.20p1 and earlier is vulnerable to an input validation (embedded newlines) in the get_process_ttyname() function resulting in information disclosure and command execution. | [email protected] | 8.2 | 0.15% | 2017-06-05 | 2026-05-13 |
