Description Sam Fowler 2018-09-12 01:33:04 EDT

A buffer overflow when handling string concatenation in util_acl_to_str in tools/util.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.
