The remote Virtuozzo host is missing a security update.
According to the version of the vzkernel package and the readykernel-patch installed, the Virtuozzo installation on the remote host is affected by the following vulnerability : - [3.10.0-862.9.1.vz7.63.3 to 3.10.0-1062.4.2.vz7.116.7] xfs: potential denial of service caused by missing unlock operation in xfs_setattr_nonsize(). It was discovered that xfs_setattr_nonsize() would not unlock 'ILOCK' lock if the user or group were out of their disk quota. As a result, any subsequent operation, which needed to take 'ILOCK', would get stuck, leading to a denial of service. Note that Tenable Network Security has extracted the preceding description block directly from the Virtuozzo security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
