OctoRPKI tries to load the entire contents of a repository in memory, and in the case of a GZIP bomb, unzip it in memory, making it possible to create a repository that makes OctoRPKI run out of memory (and thus crash).
Debian Linux Security Advisory 5041-1 - Multiple vulnerabilities were discovered in Cloudflare's RPKI validator, which could result in denial of service or path traversal.
