NVD Description

Note: Versions mentioned in the description apply only to the upstream elastic-connectors-fips-9.5 package and not the elastic-connectors-fips-9.5 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

The MongoDB Python Driver's binary accelerator can read outside a buffer when an application decodes malformed BSON containing a truncated regular-expression element without a trailing NUL byte. An actor who can supply BSON to the documented decode or decode_all API can cause the application process to terminate when the C extension is loaded. The driver's normal database wire-protocol path does not reach this code.
