Description Sam Fowler 2018-09-12 05:21:33 UTC

Several buffer overflows when handling responses from a Muscle Card in muscle_list_files in libopensc/card-muscle.c in OpenSC before 0.19.0-rc1 could be used by attackers able to supply crafted smartcards to cause a denial of service (application crash) or possibly have unspecified other impact.
