Red Hat Security Advisory 2014-1507-02 - TrouSerS is an implementation of the Trusted Computing Group's Software Stack specification. You can use TrouSerS to write applications that make use of your TPM hardware. TPM hardware can create, store and use RSA keys securely, verify a platform's software state using cryptographic hashes and more. A flaw was found in the way tcsd, the daemon that manages Trusted Computing resources, processed incoming TCP packets. A remote attacker could send a specially crafted TCP packet that, when processed by tcsd, could cause the daemon to crash. Note that by default tcsd accepts requests on localhost only.
