NVD Description

Note: Versions mentioned in the description apply only to the upstream freerdp package and not the freerdp package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions are subject to an invalid offset validation leading to Out Of Bound Write. This can be triggered when the values rect-&gt;left and rect-&gt;top are exactly equal to surface-&gt;width and surface-&gt;height. eg. rect-&gt;left == surface-&gt;width && rect-&gt;top == surface-&gt;height. In practice this should cause a crash. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this vulnerability.
