Protocol Buffers Model File Vulnerability PoC
Vulnerability
DoS via Deep Nesting, OOM Bomb, and Field Explosion in Protocol Buffer model files
Files
poc_deep_nest.pb— 5,000 levels of nested embedded messages causing stack overflowpoc_oom_bomb.pb— 22 bytes, length-delimited field claiming ~2GBpoc_many_fields.pb— 100K repeated fields causing CPU/memory exhaustionbenign.pb— Clean file for comparison
Reproduce
from google.protobuf import descriptor_pool, message_factory
# Or simply:
# Deep nesting causes recursive parser to overflow stack
# OOM bomb causes parser to attempt ~2GB allocation from 22-byte file
