Vulnerability from github – Published: 2022-11-02 19:00 – Updated: 2025-05-05 15:30

Details

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 compiler and processor architecture.

Severity

7.1 (High)
