The OpenSC set of libraries and utilities provides support for working with smart cards. OpenSC focuses on cards that support cryptographic operations and enables their use for authentication, mail encryption, or digital signatures.

Security Fix(es):

  • OpenSC: Potential PIN bypass when card tracks its own login state (CVE-2023-40660)
  • OpenSC: multiple memory issues with pkcs15-init (enrollment tool) (CVE-2023-40661)
  • OpenSC: out-of-bounds read in MyEID driver handling encryption using symmetric keys (CVE-2023-4535)
