Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

vLLM versions from 0.10.2 before 0.25.0 are affected. The Nemotron-VL processors globally disable the image pixel limit in Pillow, so an unauthenticated attacker who submits a decompression-bomb image through the chat completions API can exhaust memory, crash the worker, and deny service to other users. Upgrade vLLM to version 0.25.0 or later.
