CVE-2026-91059

The GUIX JPEG software decoder enforces no ordering on JPEG markers. A file that places a second SOF0 frame header after SOS re-runs the frame header parser after the output buffer has already been allocated and its geometry latched. The decoder returns GXSUCCESS and publishes a GXPIXELMAP whose...

CVE-2026-92454

The GUIX software JPEG decoder is vulnerable to an out-of-bounds read and a non-terminating loop when GX_SOFTWARE_DECODER_SUPPORT is enabled. The decoder fails to verify that four kinds of marker segments are long enough, causing truncated segments to be read past the end of the caller's image bu...

EUVD-2026-105046

The GUIX software JPEG decoder reads four kinds of marker segment without checking that each is long enough to hold what it reads. A truncated segment is therefore read past the end of the caller's image buffer. Separately, a zero chroma sampling factor makes the block decode loop non-terminating...

CVE-2026-92454 JPEG decoder: truncated segments are read past the image buffer, and a zero sampling factor hangs the decode

The GUIX software JPEG decoder reads four kinds of marker segment without checking that each is long enough to hold what it reads. A truncated segment is therefore read past the end of the caller's image buffer. Separately, a zero chroma sampling factor makes the block decode loop non-terminating...

The GUIX JPEG software decoder enforces no ordering on JPEG markers. A file that places a second SOF0 frame header after SOS re-runs the frame header parser after the output buffer has already been allocated and its geometry latched. The decoder returns GXSUCCESS and publishes a GXPIXELMAP whose...

CVE-2026-91059 JPEG decoder: a duplicate SOF0 after SOS publishes a pixelmap that misreports its own allocation size

The GUIX JPEG software decoder enforces no ordering on JPEG markers. A file that places a second SOF0 frame header after SOS re-runs the frame header parser after the output buffer has already been allocated and its geometry latched. The decoder returns GXSUCCESS and publishes a GXPIXELMAP whose...

CVE-2026-91059

The GUIX JPEG software decoder is vulnerable to an out-of-bounds read (CWE-125) because it does not enforce ordering on JPEG markers. A crafted file containing a second SOF0 frame header after an SOS marker causes the decoder to re-run the frame header parser after the output buffer is already al...

CVE-2026-91186

A vulnerability exists in the PNG decoder because the chunk reader fails to enforce chunk ordering, allowing a second IHDR chunk to be processed. If an attacker provides a PNG file with a second IHDR chunk positioned after the IDAT chunk, the decoder rewrites the image dimensions (width, height, ...

CVE-2026-91186 PNG decoder: a duplicate IHDR chunk after IDAT resizes the image after allocation, causing a heap out-of-bounds write

The PNG chunk reader has no notion of chunk ordering. It records whether an IDAT has been seen and whether a tRNS has already supplied transparency, but nothing prevents an IHDR being read a second time. A PNG carries exactly one IHDR and it is the first chunk. A file that places a second one aft...

DEBIAN-CVE-2026-112395

Pillow is a Python imaging library. From 8.2.0 until 13.0.0, Pillow's tiled-TIFF decoder can read past the tile buffer while copying four-byte pixels. In decodeTile, libtiff can return a tile allocation smaller than the required row stride multiplied by the tile length, and Pillow's stride-and-co...

DEBIAN-CVE-2026-112398

Pillow is a Python imaging library. Prior to 13.0.0, Pillow's FlashPix JPEG-tile decoder can write decoded scanlines beyond the allocated tile buffer. FlashPix FPX JPEG decoding selects raw mode LA with two bytes per pixel, while an unrecognized JPEG mode can be decoded as JCSUNKNOWN with four...

DEBIAN-CVE-2026-112403

Pillow is a Python imaging library. Prior to 13.0.0, Pillow's JPEG decoder can write a full-width scanline into a buffer sized for a requested draft scale. ImagingJpegDecode does not verify libjpeg's actual output width and component count after scaling is requested, and an 8-bit lossless SOF3 JP...

DEBIAN-CVE-2026-112892

Pillow is a Python imaging library. From 4.1.0 until 13.0.0, Pillow's MSP RLE decoder can expand a small file into an unbounded in-memory buffer. The decoder writes run-length output to BytesIO without limiting expansion to the declared image size. An attacker can supply a crafted MSP image to an...

Heap-based Buffer Overflow

Overview Affected versions of this package are vulnerable to Heap-based Buffer Overflow via the JPEG decoder in src/libImaging/JpegDecode.c when processing a JPEG stream whose declared output width or component count exceeds the dimensions used to size the scanline buffer. Because the buffer is...
