Pillow JPEG2000 tiled decode retains a growing scratch buffer and can be used for denial of service

Summary src/libImaging/Jpeg2KDecode.c:853 accumulates totalcomponentwidth across every tile in a JPEG2000 image instead of recomputing it per tile. That accumulated value is then used in the tilebytes calculation at src/libImaging/Jpeg2KDecode.c:868, which can make the decoder grow state-buffer v...

Pillow: Decompression Bomb DoS via PdfParser.PdfStream.decode()

Summary PdfParser.PdfStream.decode in Pillow's PdfParser.py calls zlib.decompress with the bufsize parameter set to the value of the PDF stream's Length field, without any upper bound on the actual decompressed output size. Python's zlib.decompress bufsize argument is an initial output buffer hin...

CVE-2026-47275

Nanomq has a NULL pointer dereference in nni_mqttv5_msg_decode_connect() (mqtt_codec.c:1863) for versions ≤ 0.24.11. The code iterates CONNECT properties using prop instead of will_prop; when a packet has no connect-level properties but has will properties, dereferencing prop->next can SIGSEGV...
