Note: Versions mentioned in the description apply only to the upstream opensc package and not the opensc package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

Several buffer overflows when handling responses from a CAC Card in cac_get_serial_nr_from_CUID in libopensc/card-cac.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.
