Uncover a minor-importance alert regarding pants within RHEL 6, tackling a vulnerability alongside associated upgrades.
Updated trousers packages that fix one security issue, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 6

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/articles/11258

Summary

TrouSerS is an implementation of the Trusted Computing Group's Software Stack (TSS) 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 (without ever being exposed in memory), 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. (CVE-2012-0698)
Red Hat would like to thank Andrew Lutomirski for reporting this issue.
The trousers package has been upgraded to upstream version 0.3.13, which provides a number of bug fixes and enhancements over the previous version, including corrected internal symbol names to avoid collisions with other applications, fixed memory leaks, added IPv6 support, fixed buffer handling in tcsd, as well as changed the license to BSD. (BZ#633584, BZ#1074634)
All trousers users are advised to upgrade to these updated packages, which correct these issues and add these enhancements.
