AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in FreeRDP, a free implementation of the Remote Desktop Protocol. Before version 3.22.0, the URBDRC client component uses interface numbers provided by the server as array indices without checking if these indices are within valid bounds. This lack of bounds checking leads to an out-of-bounds read in the function libusb_udev_select_interface.
The issue is fixed in FreeRDP version 3.22.0.
How can this vulnerability impact me? :
An out-of-bounds read vulnerability can potentially allow an attacker to read memory locations outside the intended buffer. This can lead to information disclosure or cause the application to crash, potentially resulting in denial of service.
Given the CVSS base score of 8.7, this vulnerability is considered high severity and can have significant impact if exploited.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
