CVE-2023-22809: Apple macOS

High severity, CVSS 7.8. EPSS: 55.4% chance of exploitation in the next 30 days.

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.

Affected products

• Apple macOS: before 13.4 (fixed in 13.4)
• Debian Debian Linux: version 10.0 only; version 11.0 only
• Fedoraproject Fedora: version 36 only; version 37 only
• Sudo Project Sudo: from 1.8.0, before 1.9.12 (fixed in 1.9.12); version 1.9.12 only
