MongoDB C Driver bson library may be susceptible to buffer overflow
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. This issue affected libbson versions prior to 1.27.5, MongoDB Server v8.0 versions prior to 8.0.1 and MongoDB Server v7.0 versions prior to 7.0.16
MongoDB C Driver bson_string_append may be vulnerable to a buffer overflow
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. This issue affects libbson versions prior to 1.27.1
MongoDB C Driver bson_strfreev may be susceptible to integer overflow
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
MongoDB client C Driver may infinitely loop when validating certain BSON input data
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. This issue affects All MongoDB C Driver versions prior to versions 1.25.0.
Some MongoDB Drivers may publish events containing authentication-related data to a command listener configured by an application
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).
This issue affects the MongoDB C Driver 1.0.0 prior to 1.17.7, MongoDB PHP Driver 1.0.0 prior to 1.9.2, MongoDB Swift Driver 1.0.0 prior to 1.1.1, MongoDB
_bson_iter_next_internal in bson-iter.c in libbson 1.12.0, as used in MongoDB mongo-c-driver and other products, has a heap-based buffer over-read via a crafted bson buffer.
