CVE-2026-55191
FreeRDP: FreeRDP: Arbitrary code execution via heap-buffer-overflow in AVC444 YUV buffer allocation
Einstufung nach Quelle
Trivys eigenes Label ist CRITICAL. Kritisch laut NVD. Niedriger laut Red Hat (hoch), Amazon (hoch), Ubuntu (mittel).
Beschreibung
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.0, FreeRDP clients that negotiate RDPGFX AVC444 with an H.264 decoder backend calculate the intermediate YUV444 allocation size in libfreerdp/codec/h264.c with 32-bit multiplication in avc444_ensure_buffer. A malicious RDP server can supply surface dimensions for which piDstStride multiplied by padDstHeight wraps to a small nonzero value, causing winpr_aligned_recalloc to allocate an undersized buffer before YUV420CombineToYUV444 writes using the actual stride and rectangle dimensions. This can cause a client crash and may permit code execution through attacker-influenced heap corruption. This issue is fixed in version 3.27.0.
