Novell eDirectory for Linux Stack Overflow
------------------------------------------------------------------------


SUMMARY

<http://www.novell.com/products/edirectory/> Novell eDirectory is "the
foundation for the world's largest identity management deployments. With
eDirectory, businesses lay the groundwork for secure identity management
solutions and multi-platform network services". A vulnerability allows
remote attackers to execute arbitrary code on vulnerable installations of
Novell eDirectory for Linux. Authentication is not required to exploit
this vulnerability.

DETAILS

Vulnerable Systems:
* Novell eDirectory version 8.8.1

Immune Systems:
* Novell eDirectory version 8.8.2
* Novell eDirectory version 8.7.3.10 (8.7.3 SP10)

The specific flaw exists in the libnldap library. When a large LDAP
delRequest message is sent, a stack overflow occurs overwriting a function
pointer. This results in a situation allowing the execution of arbitrary
code.
