UBUNTU-CVE-2025-4565 (CVE-2025-4565)

Vulnerability from osv_ubuntu – Published: 2025-06-16 15:15 – Updated: 2026-04-22 07:53 – Source website
VLAI
Details

Any project that uses Protobuf Pure-Python backend to parse untrusted Protocol Buffers data containing an arbitrary number of recursive groups, recursive messages or a series of SGROUP tags can be corrupted by exceeding the Python recursion limit. This can result in a Denial of service by crashing the application with a RecursionError. We recommend upgrading to version =>6.31.1 or beyond commit 17838beda2943d08b8a9d4df5b68f5f04f26d901
