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:
Michael Thumann has reported a vulnerability in sipXtapi, which
potentially can be exploited by malicious people to compromise a
user's system.

The vulnerability is due to a boundary error when parsing the "CSeq"
field and can be exploited to cause a buffer overflow via a packet
with an overly long "CSeq" field (larger than 24 bytes).

Successful exploitation may allow execution of arbitrary code.
