medium Tenable Cloud Security Plugin ID 477601

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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.
