freerdp: FreeRDP: Out-of-bounds write in planar bitmap decoder allows arbitrary code execution

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. The planar bitmap decoder contains an out-of-bounds heap write vulnerability when processing RLE planar data. A remote attacker could exploit this by providing specially crafted RLE planar data, leading to an...

UBUNTU-CVE-2026-45700

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, freerdpbitmapdecompressplanar validates the X destination coordinate nXDst against the...

CVE-2026-45700

FreeRDP (prior to 3.26.0) has a heap-buffer-overflow in the planar bitmap decoder. The bug occurs in freerdp_bitmap_decompress_planar() validating X destination coordinate against nDstStep; an attacker can bypass the check with large nDstStep and nXDst, causing planar_decompress_plane_rle() to wr...
