There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - The MongoDB C Driver's legacy GridFS API accepts malformed file metadata from the database without
    adequate validation. Crafted documents in a GridFS collection may cause any application that reads those
    files via the legacy API to either crash (via a division-by-zero) or silently leak process memory contents
    (via an out-of-bounds read). (CVE-2026-9100)

  - A compromised third party cloud server or man-in-the-middle attacker could send a malformed HTTP response
    and cause a crash in applications using the MongoDB C driver. (CVE-2026-4359)

  - A weakness in the MongoDB C Driver allows special elements in caller-supplied database and collection name
    components to pass without sanitization when the driver composes the target namespace for an operation. An
    application that incorporates untrusted input into these name components can have operations directed at a
    resource other than the one intended. (CVE-2026-81524)

  - An incorrect numeric conversion in the JSON parsing component of the MongoDB C Driver's BSON library may
    cause an unusually large text value to be silently shortened, or the corresponding field to be omitted,
    while the parsing operation still reports success and returns no error. An unauthenticated party who can
    supply the input processed by an application that uses this component may cause that application to hold
    data that does not match what was submitted, which may result in unintended alteration of data.
    (CVE-2026-84963)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-146965 advisory.

    A memory-handling error in the BSON-to-JSON conversion helpers of the MongoDB C Driver can write a small     number of bytes past the end of a heap buffer when a binary field is encoded and the output is cut short     at a caller-configured length limit. A party who supplies the document content, with no privileges on the     application that links the driver, may cause a small amount of data outside the intended buffer to be     altered.
