Description

This security bulletin contains information about 3 secuirty vulnerabilities.

1) Integer overflow (CVE-ID: CVE-2024-40635)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to integer overflow when handling a UID:GID larger than the maximum 32-bit signed integer. A local user can pass a large user identifier value to the application, trigger an integer overflow and execute arbitrary code on the target system.

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) Resource exhaustion (CVE-ID: CVE-2025-27144)

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

The vulnerability exists due to application does not properly control consumption of internal resources when parsing JWS and JWE input. A remote attacker can pass specially crafted data to the application, trigger resource exhaustion and perform a denial of service (DoS) attack.
