A security fix for Ruby was released for SLE-12-SP2, SP3, SP4 and SP5... that broke YaST.
The fix for SP2 was introduced in #242 and #243. The original plan was to not port that fix to the SLE-12-SP3 branch. But after some discussions in bsc#1172848, it was decided to make it available for SLE-12-SP3-LTSS.
Tested manually in a SLE-12-SP3-LTSS. Verified it indeed fixes the problem.
