vertx-redis-client is vulnerable to Denial of Service (DoS)
59
CVE Score
Medium
Denial of Service (DoS)
TL;DR
The RESP parser in vertx-redis-client allocates an array from the length a Redis server declares for an array, push, or attribute, and it does not cap that length. A Redis server, or a host on the path of an unencrypted connection, can name a huge length and force an allocation that exhausts the heap and stops the event loop. The fix rejects declared lengths above a maximum before it allocates the array.
How do I fix this?
Upgrade the io.vertx:vertx-redis-client library to the patch version.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and the client connects to a Redis server you do not trust.
