2DescriptionNVD
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.
AnalysisAI
The mongo-go-driver's GSSAPI authentication wrapper on Linux and macOS contains a heap buffer over-read vulnerability stemming from improper handling of non-null-terminated GSSAPI buffers, allowing authenticated attackers to read sensitive memory content. This vulnerability affects applications using Go-based MongoDB drivers with Kerberos authentication enabled and could lead to information disclosure of heap memory. …
