Memory leak in DB2 sqlcctcpgetbuffer process, vulnerability or not?

[Henk van de Tillaerdt <vandetillaerdt () gmail com>]

Sun released an alert about a memory leak in the sqlcctcpgetbuffer
process of DB2:
http://www-1.ibm.com/support/docview.wss?rs=71&context=SSEPGG&dc=D600&uid=swg21205583&loc=en_US&cs=utf-8&lang=en

I'm wondering, is this a vulnerability or not? Is it possible for an
attacker to exploit this? If so, how would this be possible? Does the
attacker needs an account?

Maybe someone can help me with this one.

Thanks.
