Updated pcsc-lite packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

PC/SC Lite provides a Windows SCard compatible interface for communicating with smart cards, smart card readers, and other security tokens.

Multiple buffer overflow flaws were discovered in the way the pcscd daemon, a resource manager that coordinates communications with smart card readers and smart cards connected to the system, handled client requests. A local user could create a specially crafted request that would cause the pcscd daemon to crash or, possibly, execute arbitrary code. (CVE-2010-0407, CVE-2009-4901)

Users of pcsc-lite should upgrade to these updated packages, which contain a backported patch to correct these issues. After installing this update, the pcscd daemon will be restarted automatically.

The remote Redhat Enterprise Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2010:0533 advisory.

  - pcsc-lite: Privilege escalation via specially-crafted client to PC/SC Smart Card daemon messages     (CVE-2009-4901, CVE-2010-0407)

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

Multiple vulnerabilities has been found and corrected in pcsc-lite :

The MSGFunctionDemarshall function in winscard_svc.c in the PC/SC Smart Card daemon (aka PCSCD) in MUSCLE PCSC-Lite before 1.5.4 might allow local users to cause a denial of service (daemon crash) via crafted SCARD_SET_ATTRIB message data, which is improperly demarshalled and triggers a buffer over-read, a related issue to CVE-2010-0407 (CVE-2009-4901).

Buffer overflow in the MSGFunctionDemarshall function in winscard_svc.c in the PC/SC Smart Card daemon (aka PCSCD) in MUSCLE PCSC-Lite 1.5.4 and earlier might allow local users to gain privileges via crafted SCARD_CONTROL message data, which is improperly demarshalled. NOTE: this vulnerability exists because of an incorrect fix for CVE-2010-0407 (CVE-2009-4902).

Multiple buffer overflows in the MSGFunctionDemarshall function in winscard_svc.c in the PC/SC Smart Card daemon (aka PCSCD) in MUSCLE PCSC-Lite before 1.5.4 allow local users to gain privileges via crafted message data, which is improperly demarshalled (CVE-2010-0407).

Packages for 2008.0 and 2009.0 are provided as of the Extended Maintenance Program. Please visit this link to learn more:

The updated packages have been patched to correct these issues.

An update to address a buffer overflow which could allow a local attacker to elevate privileges.

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.

It was discovered that the PC/SC service did not correctly handle malformed messages. A local attacker could exploit this to execute arbitrary code with root privileges.

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

It was discovered that PCSCD, a daemon to access smart cards, was vulnerable to a buffer overflow allowing a local attacker to elevate his privileges to root.

This update of pcsc-liste fixes two vulnerabilities :

  - CVE-2009-4901: local denial of service (daemon crash)     via crafted SCARD_SET_ATTRIB message data, a related     issue to CVE-2010-0407.

  - CVE-2009-4902: a buffer overflow might allow local users     to gain privileges via crafted SCARD_CONTROL message     data, this vulnerability exists because of an incorrect     fix for CVE-2010-0407.
