Severity:	normal
Title:	OpenSC: Multiple vulnerabilities
Date:	08/01/2009
Bugs:	#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	Vulnerable	Unaffected	Architecture(s)
dev-libs/opensc	< 0.11.8	>= 0.11.8	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:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-libs/opensc-0.11.8"
