Novell eDirectory LDAP Extended Request Message Buffer Overflow Vulnerability

Novell eDirectory is prone to a buffer-overflow vulnerability because it fails to adequately bounds-check user-supplied data before copying it to an insufficiently sized buffer.

Attackers can exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts will result in a denial-of-service condition.

This issue affects eDirectory 8.8.1 and prior as well as 8.7.3.9 and prior versions for Linux, Solaris, and Windows platforms.
