Description Marian Rehak 2023-09-01 10:55:34 UTC 
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions are subject to an Out-Of-Bounds Write in the `writePixelBGRX` function. This issue is likely down to incorrect calculations of the `nHeight` and `srcStep` variables. This issue has been addressed in version 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this issue.

Comment 2 Ondrej Holy 2023-09-01 14:06:49 UTC 
The upstream report says that this vulnerability affects just version 3. But freerdp 3 isn't included in Fedora, or RHEL. So I think that this can be closed, can't be?
