Description Florian Weimer 2015-08-24 14:32:30 UTC
It was discovered that the protobuf library and code generated by the
protobuf compiler store size information in an int variable, which may
truncate size values on 64-bit architectures, leading to a heap-based
buffer overflow.


This issue was discovered by Florian Weimer of Red Hat Product Security.
