AlienVault OTX Vulnerabilities

AlienVault OTX Malware

NULL pointer dereference in the dacp_reply_playqueueedit_clear function in src/httpd_dacp.c in owntone-server through commit 6d604a1 (newer commit after version 28.12) allows remote attackers to cause a Denial of Service (crash).

CVE-2025-57156 identifies a NULL pointer dereference vulnerability in the owntone-server project, specifically within the dacp_reply_playqueueedit_clear function located in src/httpd_dacp.c. This function is part of the HTTP daemon handling DACP requests, which are used for remote control of audio playback queues. The vulnerability was introduced after version 28.12, notably in commit 6d604a1. When a specially crafted DACP request is sent to the server, the function attempts to access or clear a pointer that is NULL, causing the server process to crash. This results in a denial of service condition, rendering the media server unavailable until restarted. The flaw can be triggered remotely without authentication or user interaction, making it accessible to unauthenticated attackers on the network. While no public exploits are currently known, the vulnerability poses a risk to availability for deployments relying on owntone-server for media streaming or audio control. The lack of a CVSS score indicates the need for an independent severity assessment. The vulnerability does not appear to allow code execution or data leakage, focusing impact on service disruption. The technical root cause is improper handling of null pointers in DACP request processing, a common programming error in C-based network services.
