Heap buffer overflow via mid-scan command list growth in client topology monitoring
Fix: upgrade to 1.30.12 or later (2 fixed versions below)
Impact
An out-of-bounds write in the connection-monitoring logic of the MongoDB C Driver may allow an unauthenticated party who controls name resolution and the responses of the hosts named in a client's connection string to write beyond the end of a heap buffer. This may cause the application using the driver to terminate unexpectedly.
Patches
Fixed in 1.30.12 and 2.5.5.
Workarounds
None.
