The bson_strfreev function in the MongoDB C driver library may be susceptible to an integer overflow where the function will try to free memory at a negative offset. This may result in memory corruption. This issue affected libbson versions prior to 1.26.2

The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7613-1 advisory.

    Karman Liu discovered that mongo-c-driver did not correctly handle certain memory operations. An attacker     could possibly use this issue to cause a denial of service or execute arbitrary code. (CVE-2024-6381)

    Karman Liu discovered that mongo-c-driver did not correctly handle certain memory operations. An attacker     could possibly use this issue to cause a denial of service or execute arbitrary code. This issue only     affected Ubuntu 24.04 LTS. (CVE-2024-6383, CVE-2025-0755)

    Package        : mongo-c-driver     Version        : 1.17.6-1+deb11u1     CVE ID         : CVE-2021-32050 CVE-2023-0437 CVE-2024-6381 CVE-2024-6383                      CVE-2025-0755

    Multiple vulnerabilities have been discovered in the MongoDB C Driver.

    CVE-2021-32050

        Some MongoDB Drivers may erroneously publish events containing         authentication-related data to a command listener configured by an         application. The published events may contain security-sensitive         data when specific authentication-related commands are executed.
        Without due care, an application may inadvertently expose this         sensitive information, e.g., by writing it to a log file. This issue         only arises if an application enables the command listener feature         (this is not enabled by default).

    CVE-2023-0437

        When calling bson_utf8_validate on some inputs a loop with an exit         condition that cannot be reached may occur, i.e. an infinite loop.

    CVE-2024-6381

        The bson_strfreev function in the MongoDB C driver library may be         susceptible to an integer overflow where the function will try to         free memory at a negative offset. This may result in memory         corruption.

    CVE-2024-6383

        The bson_string_append function in MongoDB C Driver may be         vulnerable to a buffer overflow where the function might attempt to         allocate too small of buffer and may lead to memory corruption of         neighbouring heap memory.

    CVE-2025-0755

        The various bson_append functions in the MongoDB C driver library         may be susceptible to buffer overflow when performing operations         that could result in a final BSON document which exceeds the maximum         allowable size (INT32_MAX), resulting in a segmentation fault and         possible application crash.

    For Debian 11 bullseye, these problems have been fixed in version     1.17.6-1+deb11u1.

    We recommend that you upgrade your mongo-c-driver packages.

    Package        : libbson-xs-perl     Version        : 0.8.4-1+deb11u1     CVE ID         : CVE-2017-14227 CVE-2018-16790 CVE-2023-0437 CVE-2024-6381                      CVE-2024-6383 CVE-2025-0755

    Several vulnerabilities have been found in libbson-xs-perl, the Perl XS     implementation of MongoDB's BSON serialization.

    CVE-2017-14227

        The bson_iter_codewscope function in bson-iter.c miscalculates a         bson_utf8_validate length argument, which allows remote attackers to         cause a denial of service (heap-based buffer over-read in the         bson_utf8_validate function in bson-utf8.c), as demonstrated by         bson-to-json.c.

    CVE-2018-16790

        _bson_iter_next_internal has a heap-based buffer over-read via a         crafted bson buffer.

    CVE-2023-0437

        When calling bson_utf8_validate on some inputs a loop with an exit         condition that cannot be reached may occur, i.e. an infinite loop.

    CVE-2024-6381

        The bson_strfreev function in the MongoDB C driver library may be         susceptible to an integer overflow where the function will try to         free memory at a negative offset. This may result in memory         corruption.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The bson_strfreev function in the MongoDB C driver library may be susceptible to an integer overflow where     the function will try to free memory at a negative offset. This may result in memory corruption. This     issue affected libbson versions prior to 1.26.2 (CVE-2024-6381)

Note that Nessus relies on the presence of the package as reported by the vendor.
