tcsd in TrouSerS before 0.3.10 allows remote attackers to cause a denial of service (daemon crash) via a crafted type_offset value in a TCP packet to port 30003.

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by a vulnerability that has been acknowledged by the vendor but will not be patched.

  - trousers: DoS vulnerability in tcsd (CVE-2012-0698)

Note that Nessus has not tested for this issue but has instead relied on the package manager's report that the package is installed.

The remote Solaris system is missing necessary patches to address security updates :

    (CVE-2012-0698)

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.

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.

The remote Oracle Linux 6 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2014-1507 advisory.

    [0.3.13-2]
    - Fix strict alias warning

    [0.3.13-1]
    - New upstream bug fix release     resolves: #633584 - Pick up latest TrouSerS package     resolves: #1074634 - Buffer overflow detected in TrouSerS daemon

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Andy Lutomirski discovered that tcsd (the TPM userspace daemon) was missing input validation. Using carefully crafted input, it can lead to a denial of service by making the daemon crash with a segmentation fault.

This update closes a small security issue where a remote user could crash tscd if it were enabled for networking. This update also has improved init scripts which should make it load quicker.

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.
