How to fix?
There is no fixed version for RHEL:7 libwinpr.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libwinpr package and not the libwinpr package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
In FreeRDP before version 2.1.2, there is a global OOB read in update_read_cache_bitmap_v3_order. As a workaround, one can disable bitmap cache with -bitmap-cache (default). This is fixed in version 2.1.2.
