Last modified
CVE-2022-43995 is a high-severity vulnerability rated 7.1/10 on the CVSS scale. 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. EPSS estimates a 0.27% chance of exploitation in the next 30 days.
