CVE-2025-24294 (GCVE-0-2025-24294)

Vulnerability from cvelistv5 – Published: 2025-07-12 03:30 – Updated: 2025-07-16 13:37

Summary

The attack vector is a potential Denial of Service (DoS). The vulnerability is caused by an insufficient check on the length of a decompressed domain name within a DNS packet. An attacker can craft a malicious DNS packet containing a highly compressed domain name. When the resolv library parses such a packet, the name decompression process consumes a large amount of CPU resources, as the library does not limit the resulting length of the name. This resource consumption can cause the application thread to become unresponsive, resulting in a Denial of Service condition.
