CVE-2023-24537
Description
A flaw was found in Golang Go, where it is vulnerable to a denial of service caused by an infinite loop due to integer overflow when calling any of the Parse functions. By sending a specially crafted input, a remote attacker can cause a denial of service.
Statement
This vulnerability has been rated Moderate because it allows denial of service condition in Go’s source code parser when processing specially crafted input containing //line directives with excessively large line numbers. Exploitation can cause the parser to enter an infinite loop, consuming CPU resources and rendering services unresponsive. While this issue does not permit code execution or data access, it poses a significant availability impact for systems processing untrusted Go source input.
Mitigation
To mitigate this issue, upgrade Go to version 1.19.8, 1.20.3, or later, where the vulnerability has been addressed.
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: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Amplification
An infinite loop will cause unexpected consumption of resources, such as CPU cycles or memory. The software's operation may slow down, or cause a long time to respond.
