CVE-2023-42465 (GCVE-0-2023-42465)
Vulnerability from nvd – Published: 2023-12-22 00:00 – Updated: 2025-11-04 21:08
VLAI?
Summary
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.
Severity ?
No CVSS data available.

CVE-2023-22809 (GCVE-0-2023-22809)
Vulnerability from nvd – Published: 2023-01-18 00:00 – Updated: 2025-04-04 15:45
VLAI?
Summary
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.
Severity ?
7.8 (High)

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=\u0027vim -- /path/to/extra/file\u0027 value."

VLAI?
Summary
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.

CVE-2021-23240 (GCVE-0-2021-23240)
Vulnerability from nvd – Published: 2021-01-12 08:17 – Updated: 2024-08-03 19:05
VLAI?
Summary
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.
Severity ?

CVE-2019-18634 (GCVE-0-2019-18634)
Vulnerability from nvd – Published: 2020-01-29 17:23 – Updated: 2024-08-05 01:54
VLAI?
Summary
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.
Severity ?
No CVSS data available.

CVE-2019-18684 (GCVE-0-2019-18684)
Vulnerability from nvd – Published: 2019-11-04 15:53 – Updated: 2024-08-05 02:02 Disputed
VLAI?
Summary
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

CVE-2023-42465 (GCVE-0-2023-42465)
Vulnerability from cvelistv5 – Published: 2023-12-22 00:00 – Updated: 2025-11-04 21:08
VLAI?
Summary
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.
Severity ?
No CVSS data available.

CVE-2023-22809 (GCVE-0-2023-22809)
Vulnerability from cvelistv5 – Published: 2023-01-18 00:00 – Updated: 2025-04-04 15:45
VLAI?
Summary
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.
Severity ?
7.8 (High)

Summary
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.

CVE-2019-18634 (GCVE-0-2019-18634)
Vulnerability from cvelistv5 – Published: 2020-01-29 17:23 – Updated: 2024-08-05 01:54
VLAI?
Summary
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.
Severity ?
No CVSS data available.

CVE-2019-18684 (GCVE-0-2019-18684)
Vulnerability from cvelistv5 – Published: 2019-11-04 15:53 – Updated: 2024-08-05 02:02 Disputed
VLAI?
Summary
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
