| summary: |- |
| Denial of service via malicious message size declaration in |
| github.com/facebook/fbthrift |
| description: |- |
| Thrift Servers preallocate memory for the declared size of messages before |
| checking the actual size of the message. This allows a malicious user to send |
| messages that declare that they are significantly larger than they actually are, |
| allowing them to force the server to allocate significant amounts of memory. |
| This can be used as a denial of service vector. |
