Descriptions

Endless recursion when handling responses from an IAS-ECC card in iasecc_select_file in libopensc/card-iasecc.c in OpenSC before 0.19.0-rc1 could be used by attackers able to supply crafted smartcards to hang or crash the opensc library using programs.

Una recursión infinita al manejar las respuestas de una tarjeta IAS-ECC en iasecc_select_file en libopensc/card-iasecc.c en OpenSC en versiones anteriores a la 0.19.0-rc1 podría ser empleada por atacantes para proporcionar smartcards manipuladas para provocar el bloqueo o el cierre inesperado de la librería opensc mediante programas.

The OpenSC set of libraries and utilities provides support for working with smart cards. OpenSC focuses on cards that support cryptographic operations and enables their use for authentication, mail encryption, or digital signatures. Issues addressed include a buffer overflow vulnerability.
