| Description | gopacket provides packet processing capabilities for Go. In version 1.6.0 and earlier, the Diameter AVP decoder computes an AVP data length by subtracting a fixed header size from an attacker-controlled AVP Length field, so a vendor-flagged AVP whose Length is smaller than the 12-byte header underflows the unsigned 32-bit value and drives an unbounded allocation of roughly 4 GiB, and two such messages in succession OOM-kill a collector, causing an unauthenticated remote denial of service. This issue is fixed in version 1.6.1. | |
