CentOS Update for systemtap CESA-2010:0124 centos5 i386

CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/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 system for systems running the Linux kernel, version 2.6. Developers can write scripts to collect data on the operation of the system. A flaw was found in the SystemTap compile server, stap-server, an optional component of SystemTap. This server did not adequately sanitize input provided by the stap-client program, which may allow a remote user to execute arbitrary shell code with the privileges of the compile server process, which could possibly be running as the root user. (CVE-2009-4273) Note: stap-server is not run by default. It must be started by a user or administrator. A buffer overflow flaw was found in SystemTap's tapset __get_argv() function. If a privileged user ran a SystemTap script that called this function, a local, unprivileged user could, while that script is still running, trigger this flaw and cause memory corruption by running a command with a large argument list, which may lead to a system crash or, potentially, arbitrary code execution with root privileges. (CVE-2010-0411) Note: SystemTap scripts that call __get_argv(), being a privileged function, can only be executed by the root user or users in the stapdev group. As well, if such a script was compiled and installed by root, users in the stapusr group would also be able to execute it. SystemTap users should upgrade to these updated Linux Distribution Packages, which contain backported patches to correct these issues.

Recommendations:
Please install the updated Linux Distribution Packages.

Detection Type:
Linux Distribution Package

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".
