http://security.gentoo.org/

Severity:	normal
Title:	OpenSC: Arbitrary code execution
Date:	01/21/2014
Bugs:	#349567
ID:	201401-18

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	Architecture(s)
dev-libs/opensc	< 0.11.13-r2	>= 0.11.13-r2	All supported architectures

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.
