NVD Description

Note: Versions mentioned in the description apply only to the upstream libfreerdp2 package and not the libfreerdp2 package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, xf_clipboard_format_equal reads freed lastSentFormats memory because xf_clipboard_formats_free (called from the cliprdr channel thread during auto-reconnect) frees the array while the X11 event thread concurrently iterates it in xf_clipboard_changed, triggering a heap use after free. Version 3.23.0 fixes the issue.
