Description

This security bulletin contains information about 3 secuirty vulnerabilities.

1) Infinite loop (CVE-ID: CVE-2024-24788)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop when processing DNS responses. A remote attacker can send a specially crafted DNS response to the application and cause denial of service conditions.

2) Input validation error (CVE-ID: CVE-2025-22870)

The vulnerability allows a remote attacker to alter application's behavior.

The vulnerability exists due to insufficient validation of an IPv6 zone ID as a hostname component, when matching hosts against proxy patterns. For instance the NO_PROXY environment variable is set to "*.example.com", a request to "[::1%25.example.com]:80` will incorrectly match and not be proxied. A remote attacker can alter application behavior and potentially  gain access to sensitive information or functionality.

3) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2025-22871)

The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.

The vulnerability exists due to improper validation of HTTP requests when handling chunked data in net/http. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.
