CVE-2025-69720
Description
A flaw was found in ncurses. This vulnerability, a buffer overflow, exists within the analyze_string() function. An attacker could potentially exploit this to execute unauthorized code on the affected system, which might lead to a denial of service in the affected application, the corruption of data, or sensitive information being revealed to an attacker.
Statement
This Moderate impact vulnerability in ncurses affects Red Hat Enterprise Linux 10.0.z and 10.1.z. A buffer overflow in the analyze_string() function, exploitable through the infocmp utility, could lead to arbitrary code execution. Red Hat Enterprise Linux 6-ELS, 7-ELS, 8.x, 9.x, and OpenShift Container Platform are not affected as the vulnerable code is not present in these versions. Exploitation of this vulnerability requires that an affected application processes malicious data; this requires either user interaction or privileges on an affected system.
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)
Integrity,Confidentiality,Availability
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
Buffer overflows often can be used to execute arbitrary code, which is usually outside the scope of the product's implicit security policy. This can often be used to subvert any other security service.
Availability
Technical Impact: Modify Memory; DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU)
Buffer overflows generally lead to crashes. Other attacks leading to lack of availability are possible, including putting the product into an infinite loop.
