Info-ZIP 'unzip' is susceptible to a filename buffer-overflow vulnerability. The application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized memory buffer.
|
|
|
|
This issue allows attackers to execute arbitrary machine code in the context of users running the affected application.
