The remote directory service is affected by multiple buffer overflows.
The remote host is running eDirectory, a directory service software from Novell. The installed version of eDirectory is affected by an integer overflow issue in ds.dlm / dhost.exe (bound by default to TCP port 524) as well as a heap-based buffer overflow that can be triggered by passing NULL search parameters to the LDAP service. An unauthenticated attacker may be able to leverage either issue to execute code on the remote host with SYSTEM privileges.
Upgrade to eDirectory 8.8.2 FTF2 / 8.7.3 SP10b or later.
