Description Sam Fowler 2018-09-12 02:46:38 EDT 
Various out of bounds reads when handling responses in OpenSC before 0.19.0-rc1 could be used by attackers able to supply crafted smartcards to potentially crash the opensc library using programs.

Created opensc tracking bugs for this issue:

Affects: fedora-all [bug 1628053]
Comment 3 Doran Moppert 2018-09-18 03:48:58 EDT 
The patch sections affecting src/libopensc/card-openpgp.c and src/libopensc/ef-gdo.c don't appear to apply to opensc-0.16.0, but the rest almost certainly do
