The MSGFunctionDemarshall function in winscard_svc.c in the PC/SC Smart Card daemon (aka PCSCD) in MUSCLE PCSC-Lite before 1.5.4 might allow local users to cause a denial of service (daemon crash) via crafted SCARD_SET_ATTRIB message data, which is improperly demarshalled and triggers a buffer over-read, a related issue to CVE-2010-0407.

Security readout for executives and security teams

This flaw can let a local user crash the PC/SC smart-card daemon on systems running PCSC-Lite before 1.5.4. It is an availability issue, not described as remote code execution. Business impact depends on whether smart cards support login, token access, or other authentication workflows. Likely exposure is limited to hosts running PCSC-Lite PCSCD before 1.5.4 with local user access. Debian and Fedora advisories indicate distribution package relevance. Environments that do not run pcscd or do not use smart-card services are less likely to be materially affected. Handle through normal vulnerability management unless smart-card authentication is business-critical. Prioritize patching where a daemon crash could block workforce login, regulated access, or token-backed operations. The available evidence does not justify emergency internet-wide response. Mitigation focus: Inventory systems running pcscd or PCSC-Lite packages.; Upgrade PCSC-Lite to 1.5.4 or a vendor-fixed backport.; Prioritize Debian and Fedora systems matching the advisory scope..
