RHSA-2014:1507 - Low: trousers security, bug fix, and enhancement update

Synopsis

Low: trousers security, bug fix, and enhancement update

Type/Severity

Security Advisory Low

Topic

Updated trousers packages that fix one security issue, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

Description

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.
