Subject: OPEN SOURCE NTFS-3G SECURITY ADVISORY NTFS3G-SA-2022-0002
Security vulnerabilities were identified in the open source NTFS-3G
built with internal libfuse (known as libfuse-lite) or libfuse2. These
vulnerabilities were confirmed and resolved. A proof-of-concept exploit
against a specific NTFS-3G build exists.
These vulnerabilities allow an attacker to execute arbitrary privileged
code, if the attacker has local access and the ntfs-3g binary is setuid
root.
We recommend installing and applying the update with the security fixes,
and advise to follow security guidance and frameworks such as NIST for
assessing and improving an organization’s abilities to prevent, detect,
and respond to security threats and cyber attacks.
AFFECTED PRODUCTS: All previous versions of open source NTFS-3G compiled
with internal libfuse (known as libfuse-lite) or libfuse2.
WORKAROUND: None
SOLUTION: Upgrade to 2022.5.17
PROJECT URL: https://github.com/tuxera/ntfs-3g
ADVISORY ID: NTFS3G-SA-2022-0002
ISSUE DATE: 2022-05-26
SEVERITY: High
CVEs: CVE-2022-30783, CVE-2022-30785, CVE-2022-30787
CVSS SCORE: 7.5
ACKNOWLEDGMENT: Thanks to Roman Fiedler for reporting the
vulnerabilities and supplying a PoC.
