OpenSC is a tools and libraries for smart cards.
Multiple stack-based buffer overflow errors have been discovered in OpenSC.
A physically proximate attacker could possibly execute arbitrary code using a specially crafted smart card.
There is no known workaround at this time.
All OpenSC users should upgrade to the latest version:
# 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.
Multiple vulnerabilities were found in OpenSC.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| dev-libs/opensc | * | < 0.11.8 | >= 0.11.8 |
OpenSC provides a set of libraries and utilities to access smart cards.
Multiple vulnerabilities were found in OpenSC:
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.
There is no known workaround at this time.
All OpenSC users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/opensc-0.11.8"
Smart cards formatted using OpenSC do not sufficiently protect the PIN, allowing attackers to reset it.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| dev-libs/opensc | * | < 0.11.6 | >= 0.11.6 |
OpenSC is a smart card application that allows reading and writing via PKCS#11.
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.
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.
There is no known workaround at this time.
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
