CVE-2023-3635
Description
A flaw was found in SquareUp Okio. A class GzipSource does not handle an exception that might be raised when parsing a malformed gzip buffer. This issue may allow a malicious user to start processing a malformed file, which can result in a Denial of Service (DoS).
Statement
Red Hat JBoss Enterprise Application Platform XP does contain Okio package but is not using GzipSource.java, which is the affected class. Red Hat support for Spring Boot is considered low impact as it's used by Dekorate during compilation process and not included in the resulting Jar.
