Upgrade thrift to version 0.25.0 or higher.
Overview
Affected versions of this package are vulnerable to Out-of-bounds Write in the transform function of the C++ transport layer when ZLIB compression is enabled on outbound frames. An attacker can cause memory corruption, potentially leading to service instability, application crashes, data disclosure, or execution of arbitrary code by sending incompressible data that expands during compression from an untrusted peer. This is only exploitable if the application explicitly enables ZLIB compression transforms on outbound frames in the C++ transport implementation.
