Gentoo Linux Security Advisory

Title: OpenSC: Multiple vulnerabilities (GLSA 200908-01)
Severity: normal
Exploitable: local
Date: August 01, 2009
Bug(s): #260514, #269920
ID: 200908-01

Synopsis


Multiple vulnerabilities were found in OpenSC.


Background


OpenSC provides a set of libraries and utilities to access smart cards.


Affected Packages

Package: dev-libs/opensc
Vulnerable: < 0.11.8
Unaffected: >= 0.11.8
Architectures: All supported architectures


Description


Multiple vulnerabilities were found in OpenSC:

• b.badrignans discovered that OpenSC incorrectly initialises private
  data objects (CVE-2009-0368).
• Miquel Comas Marti discovered
  that src/tools/pkcs11-tool.c in pkcs11-tool in OpenSC 0.11.7, when used
  with unspecified third-party PKCS#11 modules, generates RSA keys with
  incorrect public exponents (CVE-2009-1603).

Impact


The first vulnerabilty allows physically proximate attackers to bypass
intended PIN requirements and read private data objects. The second
vulnerability allows attackers to read the cleartext form of messages
that were intended to be encrypted.

NOTE: Smart cards which were initialised using an affected version of
OpenSC need to be modified or re-initialised. See the vendor's advisory
for details.


Workaround


There is no known workaround at this time.


Resolution


All OpenSC users should upgrade to the latest version:
