Recent Sudoproject Sudo Security Vulnerabilities
Sudo before 1.9.13 does not escape control characters in sudoreplay output.

Sudo before 1.9.13p2 has a double free in the per-command chroot feature.
CVE-2023-27320
7.2 - High
- February 28, 2023
Sudo before 1.9.13p2 has a double free in the per-command chroot feature.
Double-free
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)
CVE-2023-22809
7.8 - High
- January 18, 2023
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.
Improper Privilege Management
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
CVE-2022-43995
7.1 - High
- November 02, 2022
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.
Out-of-bounds Read
Sudo before 1.9.5p2 contains an off-by-one error
CVE-2021-3156
7.8 - High
- January 26, 2021
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.
off-by-five
The sudoedit personality of Sudo before 1.9.5 may
CVE-2021-23239
2.5 - Low
- January 12, 2021
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.
insecure temporary file
selinux_edit_copy_tfiles in sudoedit in Sudo before 1.9.5
CVE-2021-23240
7.8 - High
- January 12, 2021
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.
insecure temporary file
In Sudo before 1.8.26, if pwfeedback is enabled in /etc/sudoers, users
CVE-2019-18634
7.8 - High
- January 29, 2020
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.
Memory Corruption
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"
CVE-2005-4890
7.8 - High
- November 04, 2019
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.
Improper Input Validation
** DISPUTED ** Sudo through 1.8.29
CVE-2019-18684
7 - High
- November 04, 2019
** DISPUTED ** 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.
Race Condition
In Sudo before 1.8.28, an attacker with access to a Runas ALL sudoer account
CVE-2019-14287
8.8 - High
- October 17, 2019
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.
Improper Handling of Exceptional Conditions
Todd Miller's sudo version 1.8.20 and earlier is vulnerable to an input validation (embedded spaces) in the get_process_ttyname() function resulting in information disclosure and command execution.
CVE-2017-1000367
6.4 - Medium
- June 05, 2017
Todd Miller's sudo version 1.8.20 and earlier is vulnerable to an input validation (embedded spaces) in the get_process_ttyname() function resulting in information disclosure and command execution.
Race Condition
Sudo before 1.6.6 contains an off-by-one error
CVE-2002-0184
- May 16, 2002
Sudo before 1.6.6 contains an off-by-one error that can result in a heap-based buffer overflow that may allow local users to gain root privileges via special characters in the -p (prompt) argument, which are not properly expanded.
