It's a packaging mistake in a package that hasn't seen much testing.
If they include local copies of libs like libstdc++, they ought to
filter the RPM Provides. They also provide several other libs, not
limited to libgcc_s.so.1

$ repoquery --provides AdobeReader_sve|grep ^lib|wc -l
59

$ repoquery --whatprovides 'libstdc++.so.6(CXXABI_1.3)'
