CentOS Update for systemtap CESA-2009:0373 centos5 i386

Published: 2011-08-09 06:20:34
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:L/AC:M/Au:N/C:C/I:C/A:C

Summary:
The remote host is missing an update for the 'systemtap' Linux Distribution Package(s) announced via the referenced advisory.

Affected Versions:
systemtap on CentOS 5

Technical Details:
SystemTap is an instrumentation infrastructure for systems running version 2.6 of the Linux kernel. SystemTap scripts can collect system operations data, greatly simplifying information gathering. Collected data can then assist in performance measuring, functional testing, and performance and function problem diagnosis. A race condition was discovered in SystemTap that could allow users in the stapusr group to elevate privileges to that of members of the stapdev group (and hence root), bypassing directory confinement restrictions and allowing them to insert arbitrary SystemTap kernel modules. (CVE-2009-0784) Note: This issue was only exploitable if another SystemTap kernel module was placed in the 'systemtap/' module directory for the currently running kernel. Red Hat would like to thank Erik Sjölund for reporting this issue. SystemTap users should upgrade to these updated Linux Distribution Packages, which contain a backported patch to correct this issue.

Recommendations:
Please install the updated Linux Distribution Packages.

Detection Type:
Linux Distribution Package

Solution Type:
Vendor Patch

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
