These security issues were fixed:

- 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)

This is a reissue of the above security fixes for SUSE Linux Enterprise 12 GA, SP1 and SP2 LTSS,
they have already been released for SUSE Linux Enterprise Server 12 SP3.");
