Overview nltk is a Natural Language Toolkit NLTK is a Python package for natural language processing. Affected versions of this package are vulnerable to Directory Traversal via the XML index file downloader. An attacker can overwrite arbitrary files and create directories at unintended locations...

NLTK has a Downloader Path Traversal Vulnerability (AFO) - Arbitrary File Overwrite

Vulnerability Description The NLTK downloader does not validate the subdir and id attributes when processing remote XML index files. Attackers can control a remote XML index server to provide malicious values containing path traversal sequences such as ../, which can lead to: 1. Arbitrary Directo...

CVE-2006-10003

XML::Parser versions through 2.47 for Perl has an off-by-one heap buffer overflow in stserialstack. In the case stackptr == stacksize - 1, the stack will NOT be expanded. Then the new value will be written at location ++stackptr, which equals stacksize and therefore falls just outside the allocat...
