Gentoo Linux Security Advisory

Title: OpenSC: Arbitrary code execution (GLSA 201401-18)
Severity: normal
Exploitable: local
Date: January 21, 2014
Bug(s): #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: dev-libs/opensc
Vulnerable: < 0.11.13-r2
Unaffected: >= 0.11.13-r2
Architectures: 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:
Code:
# 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.
