Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Infinite loop (CVE-ID: CVE-2025-8194)

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

The vulnerability exists due to infinite loop in the “tarfile” module when handling tar archives with negative offsets. A remote attacker can pass a specially crafted tar archive to the application and consume all available system resources, resulting in a deadlock and a denial of service. 


2) Return of Wrong Status Code (CVE-ID: CVE-2025-5987)

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to incorrect handling of the wrong status code returned by the OpenSSL within the chacha20_poly1305_set_key() function when using the ChaCha20 cipher with the OpenSSL library. A remote attacker can force the library to partially initialize cipher context, leading to an undefined application's behavior.
