Hardcore Disassembler / Reverse Engineer

Reversing must be a passion as your skills will be challenged
on a daily basis and you will be working several hours
everyday in IDA, Ollydbg, and with BinDiff. Often, it is also
required that you write a PoC or even a working exploit to
prove that an issue is exploitable.

DESCRIPTION:
Two vulnerabilities have been reported in Microsoft Windows, which
can be exploited by malicious people to expose sensitive information
and compromise a vulnerable system.

1) A boundary error in the handling of Mailslots in the Server
service can be exploited to execute arbitrary code by sending a
specially crafted packet to the service.

2) An uninitialised buffer in the Server protocol driver can be
exploited to view data from the Server Message Block buffers by
sending specially crafted packets to the service.
