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.

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' value.

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. Published: November 02, 2022; 10:15:16 AM -0400 |

CVE-2021-3156 |
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. Published: January 26, 2021; 4:15:12 PM -0500 |

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. Published: January 12, 2021; 4:15:14 AM -0500 |

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. Published: January 12, 2021; 4:15:14 AM -0500 |

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 had permission to write to /etc/sudoers. Even with write permission to /proc/#####/fd/3, it would not help you write to /etc/sudoers Published: November 04, 2019; 11:15:11 AM -0500 |
