Fedora 29: FEDORA-2018-2f8f5f75f1 Critical: mongo-c-driver Buffer Over-Read

mongo-c-driver is a client library written in C for MongoDB.

**libbson 1.13.0** **Features:** * New functions to save and restore

progress of a bson_iter_t: bson_iter_key_len, bson_iter_offset, and

son_iter_init_from_data_at_offset Additional functions

bson_iter_overwrite_date_time, bson_iter_overwrite_oid, and

bson_iter_overwrite_timestamp. All fixed-length BSON values can now be

updated in place. **Bug fixes:** * Fix crash when iterating corrupt BSON.

--- **libmongoc 1.13.0** **Features:** * Report a new error code,

MONGOC_ERROR_GRIDFS_CORRUPT, when a chunk larger than chunkSize is detected.

Before, the driver had crashed with an assert. Restructure of install

directory. All mongoc headers are under mongoc/ and all bson headers are

under bson/. The preferred way of including the headers are mongoc/mongoc.h

and bson/bson.h respectively. Forwarding headers in the root are provided for

backwards compatibility. * The default CMake build type had been unspecified,

now it is RelWithDebInfo. * Support LibreSSL 2.7+. **Bug fixes:** *

mongoc_collection_replace_one is now a correctly exported symbol. * Fix

multiple issues with readConcern and writeConcern inheritance. * Fix rare

crash with mongodb+srv URIs on Windows. *

mongoc_gridfs_create_file_from_stream ignored errors while writing chunks to

the server. * The following functions should not have taken a

"bypassDocumentValidation" option in bson_t *opts, the option is now

prohibited: * mongoc_bulk_operation_insert_with_opts *

mongoc_bulk_operation_update_one_with_opts *

mongoc_bulk_operation_update_many_with_opts *

mongoc_bulk_operation_replace_one_with_opts * The heartbeat-succeeded and

heartbeat-failed events (part of SDAM Monitoring) had uninitialized

"duration" fields, they are now set correctly.
