Synopsis
Multiple vulnerabilities were found in OpenSC.
2.
Impact Information
Background
OpenSC provides a set of libraries and utilities to access smart cards.
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.
