Synopsis
========
Multiple stack-based buffer overflows have been found in OpenSC,
allowing attackers to execute arbitrary code.

Background
==========
OpenSC is a tools and libraries for smart cards.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-libs/opensc < 0.11.13-r2 >= 0.11.13-r2

Description
===========
Multiple stack-based buffer overflow errors have been discovered in
OpenSC.

Impact
======
A physically proximate attacker could possibly execute arbitrary code
using a specially crafted smart card.

Workaround
==========
There is no known workaround at this time.

Resolution
==========
All OpenSC users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/opensc-0.11.13-r2"

Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying some of these
packages.
