CVE-2015-20107

Severity CVSS v4.0:
Pending analysis
Type:
CWE-77 Command Injection
Publication date:
13/04/2022
Last modified:

Description

In Python (aka CPython) up to 3.10.8, the mailcap module does not add escape characters into commands discovered in the system mailcap file. This may allow attackers to inject shell commands into applications that call mailcap.findmatch with untrusted input (if they lack validation of user-provided filenames or arguments). The fix is also back-ported to 3.7, 3.8, 3.9
