CVE Author: NIST National Vulnerability Database

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

Summary:
Check for the Version of systemtap

Affected Versions:
systemtap on CentOS 4

Technical Details:
SystemTap is an instrumentation system for systems running the Linux kernel, version 2.6. Developers can write scripts to collect data on the operation of the system. staprun, the SystemTap runtime tool, is used for managing SystemTap kernel modules (for example, loading them). It was discovered that staprun did not properly sanitize the environment before executing the modprobe command to load an additional kernel module. A local, unprivileged user could use this flaw to escalate their privileges. (CVE-2010-4170) Note: On Red Hat Enterprise Linux 4, an attacker must be a member of the stapusr group to exploit this issue. Also note that, after installing this update, users already in the stapdev group must be added to the stapusr group in order to be able to run the staprun tool. Red Hat would like to thank Tavis Ormandy 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 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".
