Arne Welzel 5659cf18f8 MIME: Cap nested MIME analysis depth to 100 ... OSS-Fuzz managed to produce a MIME multipart message construction with thousands of nested entities (or that's what Zeek makes out of it anyhow). Prevent such deep analysis by capping at a nesting depth of 100, preventing unnecessary resource usage. A new weird named exceeded_mime_max_depth is reported when this limit is reached. This change reduces the runtime of the OSS-Fuzz reproducer from ~45 seconds to ~2.5 seconds. The test PCAP was produced from a Python script using the email package and sending the rendered version via POST to a HTTP server. Closes #208 (cherry picked from commit 4e5849fe82c6097df5d25cd1a74d69ab4fa50f46)		2024-01-19 08:22:19 -07:00
