CVE-2008-1110 in xine-lib
Summary
by MITRE
Buffer overflow in demuxers/demux_asf.c (aka the ASF demuxer) in the xineplug_dmx_asf.so plugin in xine-lib before 1.1.10 allows remote attackers to execute arbitrary code or cause a denial of service (crash) via a crafted ASF header. NOTE: this issue leads to a crash when an attack uses the CVE-2006-1664 exploit code, but it is different from CVE-2006-1664.

The vulnerability identified as CVE-2008-1110 represents a critical buffer overflow flaw within the xine-lib multimedia framework's ASF (Advanced Systems Format) demuxer component. This vulnerability specifically affects the xineplug_dmx_asf.so plugin which handles ASF file format parsing and processing. The issue exists in versions of xine-lib prior to 1.1.10, making a significant portion of deployed multimedia applications susceptible to exploitation. The flaw manifests when the ASF demuxer processes malformed ASF headers, creating a condition where attacker-controlled data can overwrite adjacent memory regions beyond the intended buffer boundaries.
The technical implementation of this vulnerability involves improper input validation within the demux_asf.c source file where the ASF header parsing routine fails to adequately check the size and structure of incoming data. When a maliciously crafted ASF file is processed, the demuxer attempts to copy data into a fixed-size buffer without proper bounds checking, leading to memory corruption that can result in arbitrary code execution or system crashes. This type of vulnerability falls under CWE-121, which specifically addresses stack-based buffer overflow conditions, and represents a classic example of unsafe memory manipulation in multimedia processing libraries. The vulnerability is particularly concerning because it allows for remote code execution, meaning an attacker could potentially compromise systems simply by tricking users into opening maliciously crafted ASF files.
The operational impact of CVE-2008-1110 extends beyond simple denial of service scenarios to include potential system compromise and arbitrary code execution capabilities. Attackers leveraging this vulnerability could execute malicious payloads on vulnerable systems, potentially gaining full control over multimedia applications and underlying operating systems. The vulnerability's connection to CVE-2006-1664 demonstrates how seemingly disparate vulnerabilities can be interconnected within complex software ecosystems, though this particular flaw represents a distinct attack vector. Systems utilizing xine-lib for media playback, including multimedia applications, web browsers with embedded media support, and streaming platforms, would be at risk. The crash conditions resulting from this vulnerability could be exploited to cause persistent denial of service attacks against multimedia services, while the code execution capability presents a more severe threat to system integrity and user security.
Mitigation strategies for CVE-2008-1110 primarily focus on immediate software updates and patches provided by xine-lib maintainers. Organizations should prioritize upgrading to xine-lib version 1.1.10 or later, which contains the necessary fixes to address the buffer overflow conditions in the ASF demuxer. Additionally, implementing network-based security controls such as content filtering and sandboxing mechanisms can provide layered protection against exploitation attempts. Security practitioners should consider deploying intrusion detection systems capable of identifying suspicious ASF file patterns and monitoring for exploitation attempts. The vulnerability serves as a reminder of the importance of input validation in multimedia processing libraries and highlights the need for robust memory safety practices in software development. From an ATT&CK framework perspective, this vulnerability maps to techniques involving code injection and privilege escalation, emphasizing the critical nature of addressing such flaws in widely-used multimedia frameworks that serve as foundational components in many computing environments.
