"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 did not properly handle RPM
installations when a destination path was a symbolic
link to a directory, possibly changing ownership and
permissions of an arbitrary directory, and RPM files
being placed in an arbitrary destination. An attacker,
with write access to a directory in which a
subdirectory will be installed, could redirect that
directory to an arbitrary location and gain root
privilege.(CVE-2017-7500)
