Update of V8 Javascript Engine to 10.7.x
The v8 Javascript engine as used in the Couchbase Server Eventing Service, View Engine, XDCR and N1QL UDFs has been updated as there’s a type confusion in versions prior to 99.0.4844.84 which allowed a remote attacker to potentially exploit heap corruption via a crafted request.
-
A crafted HTTP request to REST API can cause a backup service OOM
An extremely large (or unbounded) HTTP request body may cause the backup service to cause an OOM (out-of-memory) error.

Update of Jackson Databind to 2.13.4.2+ as used in the Analytics Service to resolve vulnerabilities

-
Couchbase Cluster Manager lacks access controls during a cluster node restart
During the start of a couchbase server node there is a short time period where the security cookie is set to “nocookie” which lacks access controls over the Erlang distribution protocol. If an attacker connects to this protocol during this period, they can execute arbitrary code remotely on any cluster node at any point of time until their connection is dropped. The executed code will be running with the same privileges as the Couchbase Server.
-
Credentials can be leaked to the logs if there is a crash during a node join.
During a node join failure, unredacted credentials of the user making the REST request can be leaked into the log files.

Upgrade of Erlang to version 24.3.4.4
When using the tls/ssl feature in couchbase server, it is possible to bypass client authentication in certain situations. Specifically, any application using the ssl/tls/dtls server, and the client certification option “{verify, verify_peer}” are affected by this vulnerability. Corrections have been released on the supported tracks with patches 23.3.4.15, 24.3.4.2, and 25.0.2 of the erlang/OTP runtime. Only clusters using certificate-based authentication are affected.
