  • Leveraging Race Conditions
    This attack targets a race condition occurring when multiple processes access and manipulate the same resource concurrently and the outcome of the execution depends on the particular order in which the access takes place. The attacker can leverage a race condition by "running the race", modifying the resource and modifying the normal execution flow. For instance a race condition can occur while accessing a file, the attacker can trick the system by replacing the original file with his version and cause the system to read the malicious file.
  • Leveraging Time-of-Check and Time-of-Use (TOCTOU) Race Conditions
    This attack targets a race condition occurring between the time of check (state) for a resource and the time of use of a resource. The typical example is the file access. The attacker can leverage a file access race condition by "running the race", meaning that he would modify the resource between the first time the target program accesses the file and the time the target program uses the file. During that period of time, the attacker could do something such as replace the file and cause an escalation of privilege.

    description From Red Hat Security Advisory 2009:0373 : Updated systemtap packages that fix a security issue are now available for Red Hat Enterprise Linux 4 and 5. This update has been rated as having moderate security impact by the Red Hat Security Response Team. 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 Sjolund for reporting this issue. SystemTap users should upgrade to these updated packages, which contain a backported patch to correct this issue.
