Runs under Unix and Windows." Product Link: http://streamripper.sourceforge.net/ ====================================================================== 4) Description of Vulnerability Secunia Research has discovered some vulnerabilities in Streamripper, which can be exploited by malicious people to compromise a user's system. 1) A boundary error exists within http_parse_sc_header() in lib/http.c when parsing an overly long HTTP header starting with "Zwitterion v". 2) A boundary error exists within http_get_pls() in lib/http.c when parsing a specially crafted pls playlist containing an overly long entry. 3) A boundary error exists within http_get_m3u() in lib/http.c when parsing a specially crafted m3u playlist containing an overly long "File" entry. Successful exploitation allows execution of arbitrary code, but requires that a user is tricked into connecting to a malicious server. ====================================================================== 5) Solution Patches should be available shortly. ====================================================================== 6) Time Table 05/11/2008 - Vendor notified. 10/11/2008 - Vendor response. 14/11/2008 - Vendor informs that fixes are ready and will be uploaded to CVS on the agreed disclosure date. 19/11/2008 - Public disclosure. ====================================================================== 7) Credits Discovered by Stefan Cornelius, Secunia Research. ====================================================================== 8) References The Common Vulnerabilities and Exposures (CVE) project has assigned CVE-2008-4829 for the vulnerabilities. ====================================================================== 9) About Secunia Secunia offers vulnerability management solutions to corporate customers with verified and reliable vulnerability intelligence relevant to their specific system configuration: http://secunia.com/advisories/business_solutions/ Secunia also provides a publicly accessible and comprehensive advisory database as a service to the security community and private individuals, who are interested in or concerned about IT-security. http://secunia.com/advisories/ Secunia believes that it is important to support the community and to do active vulnerability research in order to aid improving the security and reliability of software in general: http://secunia.com/secunia_research/ Secunia regularly hires new skilled team members.
