pillow: Pillow: Denial of Service via infinite loop during crafted MIC image parsing

A flaw was found in Pillow. This vulnerability allows a remote attacker to cause a Denial of Service DoS by supplying a specially crafted Microsoft Image Composer MIC file. When an application attempts to count or extract frames from the malicious image, an improper state reset triggers an infini...

PT-2026-132464

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.load prepare reuses the...

BIT-PILLOW-2026-112390 Pillow: Infinite loop in MIC n_frames when the embedded TIFF

Pillow is a Python imaging library. From 7.2.0 until 13.0.0, Pillow can enter an infinite loop while determining the frame count of a MIC image. MicImageFile inherits TIFF frame traversal, but MicImageFile.tell reports the OLE stream index and its seek resets TIFF frame state, so an embedded TIFF...
