CVE-2026-1110 identifies a buffer overflow vulnerability in the rtsp_parse_method function of the cijliu librtsp library, up to commit 2ec1a81ad65280568a0c7c16420d7c10fde13b04. The vulnerability arises from improper handling of input data during the parsing of RTSP methods, leading to a buffer overflow condition. This flaw can be exploited by a local attacker with low privileges, as the attack vector requires local host access but no user interaction or elevated privileges. The buffer overflow could allow an attacker to corrupt memory, potentially leading to arbitrary code execution, denial of service, or information disclosure, although the CVSS vector indicates limited confidentiality, integrity, and availability impacts. The product uses continuous delivery with rolling releases, complicating identification of affected versions and patch availability. The vendor has not responded to early disclosure attempts, and no patches or fixes have been published yet. No known exploits are currently reported in the wild. The vulnerability's medium severity rating (CVSS 4.8) reflects the local attack vector, low complexity, and limited scope of impact. Organizations using librtsp for RTSP streaming or media processing should be aware of this vulnerability and monitor for updates.

For European organizations, the impact of CVE-2026-1110 depends on the extent to which librtsp is integrated into their media streaming, video conferencing, or surveillance systems. A successful local exploit could lead to memory corruption, potentially enabling denial of service or limited code execution on affected hosts. This could disrupt critical media services or expose sensitive streaming data. Since exploitation requires local access, the threat is higher in environments where untrusted users have local system access or where systems are shared or multi-tenant. The lack of vendor response and patches increases risk exposure duration. Organizations in sectors such as telecommunications, media production, and software development—where RTSP streaming is common—may face operational disruptions or data integrity issues. The limited confidentiality impact reduces risk of large-scale data breaches, but availability and integrity concerns remain relevant. The medium severity rating suggests moderate urgency but not immediate critical threat. However, the continuous delivery model and absence of patches complicate timely remediation, increasing risk for European entities relying on this library.

1. Restrict local access to systems running applications that use the cijliu librtsp library, ensuring only trusted users have local login capabilities. 2. Implement strict access controls and monitoring on hosts processing RTSP streams to detect unusual behavior or crashes indicative of exploitation attempts. 3. Employ application sandboxing or containerization to limit the impact of potential memory corruption. 4. Conduct code audits or use runtime protection tools (e.g., ASLR, DEP) to mitigate buffer overflow exploitation risks. 5. Maintain up-to-date backups and incident response plans to quickly recover from denial of service or compromise scenarios. 6. Monitor vendor channels and security advisories closely for patches or updates, and plan for rapid deployment once available. 7. Consider alternative RTSP libraries or implementations with active maintenance and security responsiveness if feasible. 8. Educate local users and administrators about the risk of local exploitation and enforce least privilege principles to minimize attack surface.
