CWE-ID:
CWE-787 - Out-of-bounds write

Description
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary condition within plugins/sudoers/auth/passwd.c when Sudo is configured to use the crypt() password backend (e.g. when passwd authentication is enabled). A local user with access to Sudo can enter a password of 8 characters or fewer to trigger a heap-based buffer over-read and gain access to sensitive information.
Update the affected packages.
