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...

CVE-2026-55827

A flaw was found in FreeRDP. FreeRDP clients using the non-default /cache:codec:rfx option are vulnerable to a heap out-of-bounds write. A malicious Remote Desktop Protocol RDP server can exploit this by manipulating desktop stride and height values during RemoteFX decoding for Cache Bitmap V3...

CVE-2026-55827

CVE-2026-55827 affects FreeRDP prior to 3.27.1. When clients start with the non-default /cache:codec:rfx option, FreeRDP passes desktop stride/height to RemoteFX decoding for Cache Bitmap V3 data and allocates bitmap->data only for the smaller DstWidth/DstHeight in gdi_Bitmap_Decompress, enabl...

CVE-2026-55379

Pillow is a Python imaging library. Prior to 12.3.0, PIL/BdfFontFile.py bdfchar read the BBX width and height field from a BDF font file and passed attacker-controlled dimensions to Image.new without calling Image.decompressionbombcheck, bypassing Pillow's documented decompression bomb protection...

CVE-2026-54060

The issue affects Pillow (Python imaging library). In FontFile.compile(), per-glyph images were assembled into a single bitmap using Image.new("1", (xsize, ysize)) without calling Image._decompression_bomb_check(), enabling an attacker to trigger excessive memory allocation during conversion or s...
