Amazon Linux 2 Security Advisory: ALAS-2023-1985
Advisory Release Date: 2023-03-02 22:36 Pacific
Advisory Updated Date: 2023-03-07 00:21 Pacific
Severity:
Important
Issue Overview:
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-2023-22809)
Affected Packages:
sudo
