| Name | CVE-2017-17522 |
| Description | Lib/webbrowser.py in Python through 3.6.3 does not validate strings before launching the program specified by the BROWSER environment variable, which might allow remote attackers to conduct argument-injection attacks via a crafted URL. NOTE: a software maintainer indicates that exploitation is impossible because the code relies on subprocess.Popen and the default shell=False setting |

Notes
[wheezy] - jython <not-affected> (Vulnerable code is not provided in the binary package)
Lib/webbrowser.py does not validate strings before launching the program
specified by the BROWSER environment variable.
https://bugs.python.org/issue32367
Hardly an issue with security impact, as the problematic code further relies
on subprocess.Popen with the default shell=False.
