Google’s Protocol Buffers are an extensible mechanism for serializing structured data.
A vulnerability has been discovered in protobuf and protobuf-python. Please review the CVE identifiers referenced below for details.
A parsing vulnerability for the MessageSet type can lead to out of memory failures. A specially crafted message with multiple key-value per elements creates parsing issues, and can lead to a Denial of Service against services receiving unsanitized input.
There is no known workaround at this time.
All protobuf and protobuf-python users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/protobuf-3.20.3"
# emerge --ask --oneshot --verbose ">=dev-python/protobuf-python-3.19.6"
