thrift is vulnerable to Denial of Service (DoS)
82
High Risk
This Affects:
thriftTL;DR
Connection.read() in TNonblockingServer accumulates a frame from its declared length and recopies the receive buffer when a frame crosses a read boundary, with no upper bound on that length. A frame that lands on that boundary can busy-loop the server and starve other sockets. The fix enforces max_frame_size and appends into a bytearray instead of recopying the buffer.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you run a TNonblockingServer that accepts frames from network clients.
Background info
thrift is vulnerable to Denial of Service (DoS) in versions 0.11.0 - 0.24.0.
How to fix this
Upgrade the thrift library to the patch version.
