Several security vulnerabilities were fixed in opensc, a set of libraries and utilities to access smart cards that support cryptographic operations.

Out-of-bounds reads, buffer overflows and double frees could be used by attackers able to supply crafted smart cards to cause a denial of service (application crash) or possibly have unspecified other impact.

For Debian 8 'Jessie', these problems have been fixed in version 0.16.0-3+deb8u1.

We recommend that you upgrade your opensc packages.
