exempi contains code to protect against a denial-service-attack related to XML entity expansion ("billion laughs attack"), but it was not compiled into the Mageia package because BanAllEntityUsage was not defined when the package was compiled.
This has been corrected by recompiling it with the BanAllEntityUsage macro defined. The exiv2 package contains a bundled copy of the same code and has also been recompiled with the macro defined.
