Dist Fedora Esm H88
Recent updates for Fedora 37 enhance OpenSC by resolving a buffer overflow vulnerability that impacts critical tasks involving smart cards.
Fix buffer overrun vulnerability (#2211088), fixes CVE-2023-2977

Summary

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.
