The vulnerability is caused due to an integer overflow within the e-Business administration utility service when parsing authentication packets. This can be exploited to cause a heap-based buffer overflow via a specially crafted authentication packet with an overly large length value. Successful exploitation allows execution of arbitrary code. ====================================================================== 5) Solution Install E-Business Server 8.5.3 for Solaris Install E-Business Server 8.1.2 for Linux, HP-UX, AIX ====================================================================== 6) Time Table 13/08/2007 - Vendor notified. 13/08/2007 - Vendor response. 31/10/2007 - Public disclosure. ====================================================================== 7) Credits Discovered by Dyon Balding, Secunia Research. ====================================================================== 8) References The Common Vulnerabilities and Exposures (CVE) project has assigned CVE-2007-2957 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://corporate.secunia.com/ 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/ 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://corporate.secunia.com/secunia_research/33/ Secunia regularly hires new skilled team members.
