Machine-written summary

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

vouch-proxy versions before 0.48.0 are vulnerable to a denial-of-service attack. An unauthenticated attacker who sends a single HTTP request with a specially crafted cookie name can make the server attempt a very large memory allocation, crashing the process. Upgrade to vouch-proxy 0.48.0 or later.
