Pillow is a Python imaging library. From 11.0.0 until 13.0.0, multi-frame loaders can retain an ImagingCore allocation created for a narrow frame mode while a later frame of the same dimensions changes the logical mode and decoder tiles to wider RGB or CMYK data. ImageFile.loadprepare reuses the...

Pillow is a Python imaging library. Prior to 13.0.0, the TarIO initializer in src/PIL/TarIO.py accepts a negative octal member size and computes a backward seek that returns to the same 512-byte header. When the requested member name does not match, the parser repeatedly reads that header, consum...

Pillow is a Python imaging library. Prior to 13.0.0, PILfont text-width accumulation in src/imaging.c checks positive glyph advances against INTMAX but does not check negative advances against INTMIN.

pyLoad: Lack of Input Size Validation Leads to Denial of Service (DoS) and Process Termination

Description:The API rpc function in apiblueprint.py handles multipart/form-data uploads by reading the whole content of the uploaded file into memory with file.read.
