"According to the version of the keepalived package installed, the
EulerOS Virtualization installation on the remote host is affected by
the following vulnerability :
- keepalived 2.0.8 didn't check for existing plain files
when writing data to a temporary file upon a call to
PrintData or PrintStats. If a local attacker had
previously created a file with the expected name (e.g.,
/tmp/keepalived.data or /tmp/keepalived.stats), with
read access for the attacker and write access for the
keepalived process, then this potentially leaked
sensitive information.(CVE-2018-19046)
