Title:
dsextras.py : Shell Command Injection with a pkg name
Status in pygobject-2 package in Ubuntu:
New
Bug description:
Expoit screenshot attached.
The "dsextras.py" script is vulnerable in multiple functions for code
injections in the "name" of a pkg.
The script uses old and depreached python functions wich are a
security risk :
commands.getstatusoutput()
os.system()
os.popen()
Please use the subprocess module instead !
Expoit Example wich runs a xmessage command
