Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition
product of Oracle Java SE (component: Serialization). Supported versions
that are affected are Oracle Java SE: 8u351, 8u351-perf; Oracle GraalVM
Enterprise Edition: 20.3.8 and 21.3.4. Easily exploitable vulnerability
allows unauthenticated attacker with network access via multiple protocols
to compromise Oracle Java SE, Oracle GraalVM Enterprise Edition. Successful
attacks of this vulnerability can result in unauthorized update, insert or
delete access to some of Oracle Java SE, Oracle GraalVM Enterprise Edition
accessible data. Note: This vulnerability applies to Java deployments,
typically in clients running sandboxed Java Web Start applications or
sandboxed Java applets, that load and run untrusted code (e.g., code that
comes from the internet) and rely on the Java sandbox for security. This
vulnerability does not apply to Java deployments, typically in servers,
that load and run only trusted code (e.g., code installed by an
administrator). CVSS 3.1 Base Score 5.3 (Integrity impacts). CVSS Vector:
(CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N).

Notes

Author	Note
mdeslaur	only affects openjdk-8
sbeattie	from the upstream release notes: The readObject method of _DynAnyFactoryStub has been amended, such that, when reading the stringified IOR from serialized data, it will, by default, accept stringified IORs in IOR: URI format, only. As DynAnyFactory is a locally or ORB constrained type, it is not useful that serialized data should contain corbaname or corbaloc URIs. Furthermore, an ORB will prohibit the binding of a name in the INS to a DynAnyFactory IOR, as such, using a corbaname to reference an instance of DynAnyFactory is not meaningful.
