Description Sam Fowler 2018-09-12 05:39:27 UTC

A single byte buffer overflow when handling responses from an esteid Card in sc_pkcs15emu_esteid_init in libopensc/pkcs15-esteid.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.
