Description

In Couchbase Server 4.6.3 and 5.5.0, secondary indexing encodes the entries to be indexed using collatejson. When index entries contain certain characters like \t, <, >, it caused buffer overrun as encoded string would be much larger than accounted for, causing indexer service to crash and restart. This has been remedied in versions 5.1.2 and 5.5.2 to ensure buffer always grows as needed for any input.

Improper Restriction of Operations within the Bounds of a Memory Buffer

This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
