Security issues in several database libraries have been announced: http://openwall.com/lists/oss-security/2018/06/17/1 The issues in GDBM were all fixed in 1.15. Unfortunately it changes the library major, so we probably can't safely update stables releases to it. Mageia 5 is also affected.
It does include a libgdbm_compat.so.4 (the old library major). I'm not sure if that helps.
