Technical details

A vulnerability exists in the Apache Thrift c_glib language bindings due to mismatched memory management routines (CWE-762) and the release of invalid pointers (CWE-763). Specially crafted network requests can trigger an invalid pointer free operation, resulting in a fatal 'free(): invalid pointer' error that crashes the Thrift server. The attack can be executed remotely without authentication or user interaction. This issue affects all versions of Apache Thrift prior to 0.23.0. Users are advised to upgrade to version 0.23.0 to mitigate this risk.

Affected products

Apache Thrift before 0.23.0
