NVD Description

Note: Versions mentioned in the description apply only to the upstream wal-g package and not the wal-g package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

The mongo-go-driver repository contains CGo bindings for GSSAPI (Kerberos) authentication on Linux and macOS. The C wrapper implementation contains a heap out-of-bounds read vulnerability due to incorrect assumptions about string termination in the GSSAPI standard. Since GSSAPI buffers are not guaranteed to be null-terminated or have extra padding, this results in reading one byte past the allocated heap buffer.
