Malcolm’s upload-processing pipeline (scripts\/safe-extract.py) enforces entry-count, nesting-depth, and total-uncompressed-byte limits when extracting container archives (zip\/tar\/rar\/7z via libarchive), but those limits are not applied when the uploaded file is a single-stream compressed format (.gz, .bz2, .xz, .lzma, .lz) that isn’t a .tar.*-style archive. Any authenticated user permitted to upload PCAP\/log files can upload a small, highly compressible file (e.g. a gzip bomb) that decompresses to an effectively unbounded size on disk, exhausting the shared Docker volume used by OpenSearch, Logstash, Arkime, and Zeek, and disrupting the platform for all users.<\/p>\n","protected":false},"excerpt":{"rendered":"
