Description
This security bulletin contains information about 1 security vulnerability.
1) Security restrictions bypass (CVE-ID: CVE-2018-10906)
The vulnerability allows a remote attacker to bypass security restrictions on the target system.
The weakness exists due to insufficient access and privileges controls. A remote attacker can mount a FUSE file system with the 'allow_other' mount option regardless of whether 'user_allow_other' is set in the fuse configuration when SELinux is active, trick them into accessing files on that file system, bypass security restrictions and possibly cause the service to crash.
Remediation
Install update from vendor's website.
