Description
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the application. protobuf-java allowes the interleaving of
com.google.protobuf.UnknownFieldSet fields in such a way that would be
processed out of order. A small malicious payload can occupy the parser
for several minutes by creating large numbers of short-lived objects
that cause frequent, repeated pauses. A remote attacker can trick the victim into passing specially crafted data to the application and perform a denial of service attack.
Remediation
Install updates from vendor's website.
