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, which allows attackers to read the cleartext form of me…

Multiple stack-based buffer overflows in libopensc in OpenSC 0.11.13 and earlier allow physically proximate attackers to execute arbitrary code via a long serial-number field on a smart card, related to (1) card-acos5.c,…

In OpenSC pam_pkcs11 before 0.6.13, pam_sm_authenticate() wrongly returns PAM_IGNORE in many error situations (such as an error triggered by a smartcard before login), allowing authentication bypass.

pkcs15-tool in OpenSC before 0.11.6 does not apply security updates to a smart card unless the card's label matches the "OpenSC" string, which might allow physically proximate attackers to exploit vulnerabilities that th…

OpenSC before 0.11.5 uses weak permissions (ADMIN file control information of 00) for the 5015 directory on smart cards and USB crypto tokens running Siemens CardOS M4, which allows physically proximate attackers to chan…

OpenSC before 0.11.7 allows physically proximate attackers to bypass intended PIN requirements and read private data objects via a (1) low level APDU command or (2) debugging tool, as demonstrated by reading the 4601 or…
