Description

This update fixes the following security issue :

A stack-based buffer overflow flaw was found in the way PC/SC Lite smart card framework decoded certain attribute values of the Answer-to-Reset (ATR) message, received back from the card after connecting. A local attacker could use this flaw to execute arbitrary code with the privileges of the user running the pcscd daemon, via a malicious smart card inserted to the system USB port.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
