Miggo AIRoot Cause Analysis

The vulnerability stems from improper handling of compressed XML streams in the zlib driver. The key evidence is in the commit diff showing the addition of a size_limit check during inflation. The original code in ejabberd_zlib_drv.c's control function processed compressed data in a loop without size restrictions, making it vulnerable to 'billion laughs'-style compression attacks. The patch added critical size validation (die_unless(rlen < size_limit)) to prevent unbounded memory allocation during decompression.
