CVE-2022-43995: Sudo Project Sudo

High severity, CVSS 7.1. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Sudo Project Sudo: from 1.8.0, before 1.9.12 (fixed in 1.9.12); version 1.9.12 only
