GNU WGet Multiple Remote Vulnerabilities
Multiple remote vulnerabilities reportedly affect GNU wget. These issues are due to the application's failure to properly sanitize user-supplied input and to properly validate the presence of files before writing to them. The issues include: - a potential directory-traversal issue - an arbitrary file-overwriting vulnerability - a weakness caused by the application's failure to filter potentially malicious characters from server-supplied input. Via a malicious server, an attacker may exploit these issues to arbitrarily overwrite files within the current directory and potentially outside of it. This may let the attacker corrupt files, cause a denial of service, and possibly launch further attacks against the affected computer. Overwriting of files would take place with the privileges of the user that activates the vulnerable application. |
