Description Sam Fowler 2018-09-12 01:25:22 EDT
Several buffer overflows when handling responses from a TCOS Card in tcos_select_file in libopensc/card-tcos.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.
