# Unsniff Network Analyzer 1.0 (usnf) Local Heap Overflow PoC
#
# Summary: Dont just look at hex dumps and protocol trees. With Unsniff
# Network Analyzer, you can view network traffic at various levels of detail.
# View high level objects like images, video, HTML pages, VOIP calls, drill
# down to individual TCP sessions, then onto reassembled PDUs, then finally
# to individual packets. All this functionality is packed in a cool graphical
# interface.
#
# Product web page: http://www.unleashnetworks.com/unsniff/unsniff-2.html
#
# Tested on Microsoft Windows XP Professional SP3 (English)
