CVE-2020-36774
Description
A flaw was found in Glade, where the glade_gtk_box_post_create() function in plugins/gtk+/glade-gtk-box.c mishandled widget rebuilding for GladeGtkBox, potentially leading to an application crash. This flaw allows a malicious user to cause a denial of service.
Statement
The identified flaw in Glade, specifically within the glade_gtk_box_post_create() function, is assessed as a low-severity issue rather than a moderate one due to several factors. Firstly, the flaw primarily manifests as a potential application crash, which, while disruptive, does not directly lead to the execution of arbitrary code or compromise of sensitive data. Additionally, exploitation of the vulnerability requires the ability to manipulate the Glade environment, limiting its practical impact to scenarios where the attacker already has sufficient access to the system. Furthermore, the flaw is constrained to a specific function within the GTK+ plugin for Glade, reducing its overall scope and potential for widespread impact across the application.
Mitigation
Mitigation for this issue is either not available or the currently available options don't 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).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory)
An attacker could provide unexpected values and cause a program crash or arbitrary control of resource allocation, leading to excessive consumption of resources such as memory and CPU.
Confidentiality
Technical Impact: Read Memory; Read Files or Directories
An attacker could read confidential data if they are able to control resource references.
Integrity,Confidentiality,Availability
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
An attacker could use malicious input to modify data or possibly alter control flow in unexpected ways, including arbitrary command execution.
