A vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Novell eDirectory. Authentication is not required to exploit this vulnerability.
Vulnerable Systems:
* Novell eDirectory version 8.8 for All Platforms
* Novell eDirectory version 8.7.3 for All Platforms
The specific flaw exists within dhost.exe, bound by default to TCP port 524. Flawed arithmetic applied to a user-supplied value results in an integer overflow and subsequently a complete stack smash allowing an attacker to execute arbitrary code via SEH redirection.
