"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.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
