Description

An issue in protobuf-java allowed 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. We recommend upgrading libraries beyond the vulnerable versions.

Solution(s)

  • ubuntu-upgrade-libprotobuf-lite23
  • ubuntu-upgrade-libprotobuf23
  • ubuntu-upgrade-libprotoc23
