"According to the version of the vim packages installed, the EulerOS
Virtualization installation on the remote host is affected by the
following vulnerability :
- fileio.c in Vim prior to 8.0.1263 sets the group
ownership of a .swp file to the editor's primary group
(which may be different from the group ownership of the
original file), which allows local users to obtain
sensitive information by leveraging an applicable group
membership, as demonstrated by /etc/shadow owned by
root:shadow mode 0640, but /etc/.shadow.swp owned by
root:users mode 0640, a different vulnerability than
CVE-2017-1000382.(CVE-2017-17087)
