AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in NanaZip, an open source file archive software. In versions starting from 5.0.1252.0 up to but not including 6.0.1630.0, the ROMFS archive parser can enter an infinite loop due to circular NextOffset chains. This means that when processing certain specially crafted archive files, the parser gets stuck following offsets in a loop without end.
The issue is fixed in version 6.0.1630.0.
How can this vulnerability impact me? :
The infinite loop caused by circular NextOffset chains in the ROMFS archive parser can lead to denial of service conditions. Specifically, the software may become unresponsive or hang when processing maliciously crafted archive files, potentially disrupting normal operations.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
