Summary
FreeRDP: Persistent Cache bmpSize Desync - Heap OOB Write
Details

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, in persistentcachereadentryv3() in libfreerdp/cache/persistent.c, persistent->bmpSize is updated before winpralignedrecalloc(). If realloc fails, bmpSize is inflated while bmpData points to the old buffer. This issue has been patched in version 3.24.2.
