NLTK 路径遍历漏洞

NLTK is an open-source natural language toolkit developed by NLTK. It is used to support research and development in natural language processing. NLTK versions 3.9.3 and earlier contained a path traversal vulnerability. This vulnerability stemmed from the downloader’s failure to validate the subd...

capstone: Capstone: Memory corruption via unchecked vsnprintf return

A flaw was found in Capstone, a disassembly framework. An unchecked return value from vsnprintf within the SStreamconcat function allows a malicious input to manipulate the internal stream index. This can lead to a stack buffer underflow or overflow, potentially enabling a local attacker to achie...
