*** Pendiente de traducción *** BabelDOC from 0.3.61 before 0.7.0 contains a resource exhaustion vulnerability that allows remote attackers to exhaust CPU and memory by supplying unbounded bfrange and cidrange spans. Attackers can submit a crafted PDF whose embedded ToUnicode CMap declares a huge range, driving billions of loop iterations and stalling the translation worker.
