CVE-2024-53580
Description
A flaw was found in iperf. This vulnerability allows a Denial of Service (DoS) via the injection of malformed JSON data, which can result in a segmentation fault when a NULL pointer is passed to strdup().
Statement
This vulnerability marked as important severity rather than moderate due to its potential to cause a complete denial of service (DoS) by exploiting a segmentation fault through malformed JSON data. The flaw stems from improper input validation, which allows attackers to crash the server by sending invalid data that triggers memory mismanagement. Since iperf is widely used in performance testing of network systems, a DoS attack could disrupt critical operations in production environments, leading to service outages or performance degradation in large-scale networks.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Crash, Exit, or Restart
NULL pointer dereferences usually result in the failure of the process unless exception handling (on some platforms) is available and implemented. Even when exception handling is being used, it can still be very difficult to return the software to a safe state of operation.
Integrity,Confidentiality
Technical Impact: Execute Unauthorized Code or Commands; Read Memory; Modify Memory
In rare circumstances, when NULL is equivalent to the 0x0 memory address and privileged code can access it, then writing or reading memory is possible, which may lead to code execution.
