Description Marian Rehak 2023-09-01 10:42:40 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 Read in the `general_YUV444ToRGB_8u_P3AC4R_BGRX` function. This issue is likely down to insufficient data for the `pSrc` variable and results in crashes. 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 14:06:52 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?
