Vulnerability Title
Heap-buffer-overflow write in planar bitmap decoder
Vulnerability Description
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.26.0, FreeRDP's planar bitmap decoder has an out-of-bounds heap write when decoding RLE planar data. In libfreerdp/codec/planar.c, freerdp_bitmap_decompress_planar() validates the X destination coordinate nXDst against the caller-provided destination stride (nDstStep) even when it is writing into the internal temp buffer pTempData. An attacker can bypass the check with a large nDstStep and a large nXDst, causing planar_decompress_plane_rle() to write past the end of pTempData. This vulnerability is fixed in 3.26.0.

Vulnerability Title
FreeRDP 缓冲区错误漏洞
Vulnerability Description
FreeRDP是FreeRDP团队的一款开源的远程桌面协议(RDP)的实现。 FreeRDP 3.26.0之前版本存在缓冲区错误漏洞,该漏洞源于平面位图解码器在解码RLE平面数据时存在堆越界写入,攻击者可通过大的nDstStep和nXDst绕过检查,导致写入超出内部临时缓冲区末尾。
