Fedora 29 OpenSC Security Advisory: Critical Buffer Overflows Fixed

OpenSC provides a set of libraries and utilities to work with smart cards. Its

main focus is on cards that support cryptographic operations, and facilitate

their use in security applications such as authentication, mail encryption and

digital signatures. OpenSC implements the PKCS#11 API so applications

supporting this API (such as Mozilla Firefox and Thunderbird) can use it. On

the card OpenSC implements the PKCS#15 standard and aims to be compatible with

every software/card that does so, too.

Security fix for CVE-2018-16418, CVE-2018-16419, CVE-2018-16420, CVE-2018-16421,

CVE-2018-16423, CVE-2018-16424, CVE-2018-16425, CVE-2018-16426, CVE-2018-16427 +

support for RSA-PSS signatures.
