1) Introduction

"UniDataÂŽ is an extended relational data server ideal for embedding in
a variety of industry-focused solutions."

2) Bugs
=======


The unirpc service listening on port 31438 is affected by various
Denial of Service vulnerabilities regarding the access of invalid zones
of memory.

Although the first vulnerability is a memory corruption problem where
the program calls recv() using a heap buffer and a huge amount of data
to copy (like 0x7fffffe8, decided by the attacker) in my tests it
didn't result exploitable.
