PyPI: binwalk
CVE-2022-4510
Safety vulnerability ID: SFTY-20230126-64480
Safety legacy ID: pyup.io-54641
Affected versions of binwalk from 2.1.2b through 2.3.3 included are vulnerable to path traversal and remote code execution. By crafting a malicious PFS filesystem file, an attacker can trigger the PFS extractor when binwalk is run in extraction mode (-e), causing files to be extracted to arbitrary locations. The vulnerability is associated with src/binwalk/plugins/unpfs.py.
