Severity: Normal Title: OpenSC: Insufficient protection of smart card PIN Date: December 10, 2008 Bugs: #233543 ID: 200812-09
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis ========
Smart cards formatted using OpenSC do not sufficiently protect the PIN, allowing attackers to reset it.
Background ==========
OpenSC is a smart card application that allows reading and writing via PKCS#11.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/opensc < 0.11.6 >= 0.11.6
Description ===========
Chaskiel M Grundman reported that OpenSC uses weak permissions (ADMIN file control information of 00) for the 5015 directory on smart cards and USB crypto tokens running Siemens CardOS M4.
Impact ======
A physically proximate attacker can exploit this vulnerability to change the PIN on a smart card and use it for authentication, leading to privilege escalation.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All OpenSC users should upgrade to the latest version, and then check and update their smart cards:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/opensc-0.11.6" # pkcs15-tool --test-update # pkcs15-tool --test-update --update
