  1. CVE-2026-35535 high 7.8

    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.

  2. CVE-2025-32463 high 7.8 Known exploited

    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.

  3. CVE-2025-32462 high 8.8

    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.

  4. CVE-2023-7090 high 8.8

    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.

  5. CVE-2023-42465 high 7.0

    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.

  6. CVE-2023-28487 medium 5.3

    Sudo before 1.9.13 does not escape control characters in sudoreplay output.

  7. CVE-2023-28486 medium 5.3

    Sudo before 1.9.13 does not escape control characters in log messages.

  8. CVE-2023-27320 high 7.2

    Sudo before 1.9.13p2 has a double free in the per-command chroot feature.

  9. CVE-2023-22809 high 7.8

    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' value.

  10. CVE-2022-43995 high 7.1

    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.

  11. CVE-2021-3156 high 7.8 Known exploited

    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.

  12. CVE-2021-23240 high 7.8

    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.

  13. CVE-2021-23239 low 2.5

    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.

  14. CVE-2019-18634 high 7.8

    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.

  15. CVE-2005-4890 high 7.8

    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.

  16. CVE-2019-18684 high 7.0

    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 had permission to write to /etc/sudoers. Even with write permission to /proc/#####/fd/3, it would not help you write to /etc/sudoers

  17. CVE-2019-14287 high 8.8

    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.

  18. CVE-2016-7076 high 7.8

    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.

  19. CVE-2015-8239 high 7.0

    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.

  20. CVE-2017-1000368 high 8.2

    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.
