Security Bulletin
This security bulletin contains one low risk vulnerability.
1) Use-after-free
EUVDB-ID: #VU63386
Risk: Low
CVSSv4.0: 7.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2022-1011
CWE-ID:
CWE-416 - Use After Free
Exploit availability: Yes
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in the write() function of FUSE filesystem. A local user can retireve (partial) /etc/shadow hashes and execute arbitrary code with elevated privileges.
MitigationInstall updates from vendor's repository.
