Product Link: http://www.novell.com/products/openenterpriseserver/iprint.html ====================================================================== 4) Description of Vulnerability Secunia Research has discovered a vulnerability in Novell iPrint Client, which can be exploited by malicious people to compromise a user's system. The vulnerability is caused by a boundary error in the handling of the "call-back-url" parameter value for a "op-client-interface-version" operation where the "result-type" parameter is set to "url". This can be exploited to cause a stack-based buffer overflow via an overly long "call-back-url" parameter value. Successful exploitation allows execution of arbitrary code when a user visits a malicious website. ====================================================================== 5) Solution Update to version 5.44. ====================================================================== 6) Time Table 03/08/2010 - Vendor notified. 03/08/2010 - Vendor response. 16/08/2010 - Vendor provides status update. 20/08/2010 - Public disclosure. ====================================================================== 7) Credits Discovered by Carsten Eiram, Secunia Research. ====================================================================== 8) References The Common Vulnerabilities and Exposures (CVE) project has assigned CVE-2010-1527 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.
