These people now have access to some of the best the Web has to offer - including dazzling 3D games and entertainment, interactive product demonstrations, and online learning applications." Product Link: http://www.adobe.com/products/shockwaveplayer/ ====================================================================== 4) Description of Vulnerability Secunia Research has discovered a vulnerability in Adobe Shockwave Player, which may be exploited by malicious people to compromise a user's system. The vulnerability is caused by a logic error in TextXtra.x32 when parsing "DEMX" chunks. This can be exploited to cause a heap-based buffer overflow via a specially crafted Director file as a function does not reallocate a buffer to contain a section of data as expected, but another function to still copy chunk data into the insufficiently sized buffer. Successful exploitation allows execution of arbitrary code. ====================================================================== 5) Solution Update to version 11.5.9.615. ====================================================================== 6) Time Table 07/09/2010 - Vendor notified. 07/09/2010 - Vendor response. 26/10/2010 - Status update requested. 29/10/2010 - Public disclosure. ====================================================================== 7) Credits Discovered by Carsten Eiram, Secunia Research. ====================================================================== 8) References The Common Vulnerabilities and Exposures (CVE) project has assigned CVE-2010-2582 for the vulnerability. ====================================================================== 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.
