CVE-2017-7500: 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 (bsc#943457).
CVE-2017-7501: rpm used 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 (bsc#943457)
