"According to the version of the rpm packages installed, the EulerOS
installation on the remote host is affected by the following
vulnerability :
- It was found that rpm uses temporary files with
predictable names when installing an RPM. An attacker
with ability to write in a directory where files will
be installed could create symbolic links to an
arbitrary location and modify content, and possibly
permissions to arbitrary files, which could be used for
denial of service or possibly privilege
escalation.(CVE-2017-7501)
