Security Bulletin
Summary
The connect image in IBM Security Verify Information Queue (ISIQ) v10.0.2 uses a Confluent-provided Apache Log4j library. The library includes a log-viewing component known as Chainsaw that has two deserialization flaws. ISIQ v10.0.3 upgraded its connect image to specify a newer Apache Log4j library that corrects the Chainsaw vulnerabilities. (CVE-2020-9493, CVE-2022-23307)
