Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Permissions, Privileges, and Access Controls
EUVDB-ID: #VU60004
Risk: Low
CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2021-3995
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a local user to bypass implemented security restrictions.
The vulnerability exists due to improper parsing of the /proc/self/mountinfo file in libmount. A local user can unmount other user's filesystems that are either world-writable themselves or mounted in a world-writable directory.
Update the affected package libeconf, shadow and util-linux to the latest version.
