------------------------------------------------------------------------- Debian LTS Advisory DLA-4175-1 [email protected] https://www.debian.org/lts/security/ Roberto C. Snchez May 20, 2025 https://wiki.debian.org/LTS
-------------------------------------------------------------------------

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.
