CVE-2007-4337 in Streamripper
Summary
by MITRE
Multiple buffer overflows in the httplib_parse_sc_header function in lib/http.c in Streamripper before 1.62.2 allow remote attackers to execute arbitrary code via long (1) Location and (2) Server HTTP headers, a different vulnerability than CVE-2006-3124.

The vulnerability identified as CVE-2007-4337 represents a critical buffer overflow flaw in the Streamripper media streaming client software. This vulnerability specifically affects the httplib_parse_sc_header function located within the lib/http.c source file of Streamripper versions prior to 1.62.2. The flaw manifests when the application processes HTTP headers, particularly the Location and Server headers, which are commonly used in HTTP responses during web communications and streaming operations. These headers are routinely encountered in various network protocols and are essential for proper HTTP request handling and response parsing.
The technical implementation of this vulnerability stems from inadequate input validation and buffer management within the httplib_parse_sc_header function. When Streamripper receives HTTP responses containing excessively long Location or Server headers, the application fails to properly bounds-check the input data before copying it into fixed-size buffers. This classic buffer overflow condition occurs because the software assumes that incoming HTTP headers will not exceed predetermined length limits, creating a scenario where maliciously crafted headers can overwrite adjacent memory locations. The vulnerability is categorized under CWE-121, which specifically addresses stack-based buffer overflow conditions, and aligns with ATT&CK technique T1059.007 for execution through command injection mechanisms.
The operational impact of this vulnerability extends beyond simple application instability, as it provides remote attackers with the capability to execute arbitrary code on systems running vulnerable versions of Streamripper. This remote code execution vulnerability enables attackers to gain full control over affected systems, potentially leading to complete compromise of the machine. The attack vector requires only that an attacker can influence HTTP responses received by Streamripper, which is feasible in many network environments where the software might encounter untrusted web content or be used in scenarios involving malicious servers. The vulnerability is distinct from CVE-2006-3124, indicating that this represents a separate code path or implementation flaw that requires independent remediation efforts.
Mitigation strategies for CVE-2007-4337 primarily focus on immediate software updates to Streamripper version 1.62.2 or later, which contains the necessary patches to address the buffer overflow conditions. Organizations should also implement network monitoring to detect unusual HTTP header patterns that might indicate exploitation attempts, and consider deploying intrusion detection systems capable of identifying malformed HTTP responses targeting this specific vulnerability. Additionally, administrators should review and restrict Streamripper's network access where possible, limiting exposure to untrusted web resources and ensuring that the application runs with minimal necessary privileges to reduce potential impact if exploitation occurs. The fix typically involves implementing proper input validation and bounds checking for HTTP header processing, ensuring that buffer sizes are adequate for expected input lengths while maintaining compatibility with legitimate use cases.
