[!] Unsupported instruction lodsd #13

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
++++++++++++++++++++++++++++++++++++++
1. Try to emulate a binary containing a lodsd assembly instruction (I packed a 
"Hello, World!" program with UPX and the packed image contained a lodsd 
instruction (BTW, I guess the last detail is not pertinent). See attached 
binary hello_upx_packed.exe.
2. See step 1.
3. See Step 2.

What is the expected output? What do you see instead?
+++++++++++++++++++++++++++++++++++++++++++++++++++++
I expect emulation to do just fine. Instead, I get the error (missing feature 
?):
[!] Unsupported instruction lodsd

What version of the product are you using? On what operating system?
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
I'm using the latest version (I've found no version info about pyemu, on the 
net, or in the source), running on Windows 7 Starter Edition.

Please provide any additional information below.

See attached binary hello_upx_packed.exe.
