Severity:	low
Title:	protobuf-java: Denial of Service
Date:	01/11/2023
Bugs:	#876903
ID:	202301-09

Synopsis

A vulnerability has been discovered in protobuf-java which could result in denial of service.

Background

protobuf-java contains the Java bindings for Google's Protocol Buffers.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
dev-java/protobuf-java	< 3.20.3	>= 3.20.3	All supported architectures

Description

Inputs containing multiple instances of non-repeated embedded messages with repeated or unknown fields causes objects to be converted back and forth between mutable and immutable forms, resulting in potentially long garbage collection pauses.

Impact

Crafted input can trigger a denial of service via long garbage collection pauses.

Workaround

There is no known workaround at this time.

Resolution

All protobuf-java users should upgrade to the latest version:

          # emerge --sync
          # emerge --ask --oneshot --verbose ">=dev-java/protobuf-java-3.20.3"
