Description
An out-of-bounds heap write can occur when JSON lookup is enabled. This happens when a JSON operator processes malformed JSON within an untrusted header due to an incorrect implementation of backslash skipping.
Recommendations
Update to version 4.99.2 or later.
As a temporary mitigation, disable the JSON lookup feature.
Fix
DoS
Memory Corruption
