CVE-2024-8375Network attack vector

Code execution via VARIANT vtable overwrite

Published Sep 19, 2024 · Updated Sep 19, 2024

Deserialization in Google Reverb before commit 6a0dcf4 allows remote attackers to execute code through a crafted VARIANT tensor. Tensor decompression allocates C++ VARIANT objects, then copies attacker-controlled tensor_content bytes over their vtable pointers. InsertStream and SampleStream are unauthenticated by default; execution occurs when a client samples the stored tensor and invokes a method or destructor.
