FreeRDP Heap Buffer Overflow Vulnerability (CNVD-2026-16033)

FreeRDP is an open source Remote Desktop Protocol RDP implementation library and client . FreeRDP suffers from a heap buffer overflow vulnerability. The vulnerability arises due to an out-of-bounds heap memory write due to a bmpSize synchronization error in the persistent cache. An attacker can...

UBUNTU-CVE-2026-33987

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...

CVE-2026-33987

CVE-2026-33987 affects FreeRDP prior to version 3.24.2. The vulnerability is caused by a synchronization issue in persistent_cache_read_entry_v3(): bmpSize is updated before winpr_aligned_recalloc(), so if realloc fails, bmpSize can be inflated while bmpData still points to the old buffer, enabli...
