Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The geoip-processor Maven package in OpenSearch Data Prepper, versions 2.4.0 up to 2.12.2, uses the deprecated "SSL" identifier when creating SSL contexts for downloading GeoIP databases, which could allow weaker SSL protocols to be negotiated. The source describes the attack in general terms and does not detail how it would be carried out. Upgrade to geoip-processor 2.12.2, which contains the fix. The source lists no other workaround beyond ensuring the Java runtime disables deprecated SSL protocols.
