SynopsisThe remote Virtuozzo host is missing a security update.
DescriptionAccording to the version of the parallels-server-bm-release / shaman / vzkernel / etc packages installed, the Virtuozzo installation on the remote host is affected by the following vulnerability :
- A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the Linux kernel that allows local users to create files with an unintended group ownership and with group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a certain group and is writable by a user who is not a member of this group. This can lead to excessive permissions granted in case when they should not.
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.
SolutionUpdate the affected parallels-server-bm-release / shaman / vzkernel / etc package.
