Security Bulletin
This security bulletin contains one low risk vulnerability.
1) Out-of-bounds write
EUVDB-ID: #VU68973
Risk: Low
CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2022-43995
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
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 package sudo to the latest version.
