Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 36 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-e098cdb4a1 advisory.

 # New in release [OpenJDK 8u362](https://bit.ly/openjdk8u362) (2023-01-17)

 ## CVEs Fixed

 - CVE-2023-21830
 - CVE-2023-21843

 ## Security Fixes

 - JDK-8285021: Improve CORBA communication
 - JDK-8286496: Improve Thread labels
 - JDK-8288516: Enhance font creation
 - JDK-8289350: Better media supports
 - JDK-8293554: Enhanced DH Key Exchanges
 - JDK-8293598: Enhance InetAddress address handling
 - JDK-8293717: Objective view of ObjectView
 - JDK-8293734: Improve BMP image handling
 - JDK-8293742: Better Banking of Sounds
 - JDK-8295687: Better BMP bounds

 ## Major Changes

 ### JDK-8295687: Better BMP bounds

 Loading a linked ICC profile within a BMP image is now disabled by default. To re-enable it, set the new system property `sun.imageio.bmp.enabledLinkedProfiles` to `true`. This new property replaces the old property, `sun.imageio.plugins.bmp.disableLinkedProfiles`.

 ### JDK-8293742: Better Banking of Sounds

 Previously, the SoundbankReader implementation, `com.sun.media.sound.JARSoundbankReader`, would download a JAR soundbank from a URL. This behaviour is now disabled by default. To re-enable it, set the new system property `jdk.sound.jarsoundbank` to `true`.

 ### JDK-8285021: Improve CORBA communication

 The JDK's CORBA implementation now refuses by default to deserialize objects, unless they have the `IOR:` prefix. The previous behaviour can be re-enabled by setting the new property `com.sun.CORBA.ORBAllowDeserializeObject` to `true`.

 ### [JDK-8269039](https://bugs.openjdk.org/browse/JDK-8269039): Disabled SHA-1 Signed JARs

 JARs signed with SHA-1 algorithms are now restricted by default and created as if they were unsigned. This applies to the algorithms used to digest, sign, and optionally timestamp the JAR. It also applies to the signature and digest algorithms of the certificates in the certificate chain of the code signer and the Timestamp Authority, and any CRLs or OCSP responses that are used to verify if those certificates have been revoked. These restrictions also apply to signed JCE providers.

 To reduce the compatibility risk for JARs that have been previously timestamped, there is one exception to this policy:

 - Any JAR signed with SHA-1 algorithms and timestamped prior to January 01, 2019 will not be restricted.

 This exception may be removed in a future JDK release. To determine if your signed JARs are affected by this change, run:
 ~~~ $ jarsigner -verify -verbose -certs ~~~ on the signed JAR, and look for instances of SHA1 or SHA-1 and disabled and a warning that the JAR will be treated as unsigned in the output.

 For example:
 ~~~ Signed by CN=Signer Digest algorithm: SHA-1 (disabled) Signature algorithm: SHA1withRSA (disabled), 2048-bit key

 WARNING: The jar will be treated as unsigned, because it is signed with a weak algorithm that is now disabled by the security property:

 jdk.jar.disabledAlgorithms=MD2, MD5, RSA keySize < 1024, DSA keySize < 1024, SHA1 denyAfter 2019-01-01 ~~~ JARs affected by these new restrictions should be replaced or re-signed with stronger algorithms.

 Users can, *at their own risk*, remove these restrictions by modifying the `java.security` configuration file (or override it by using the `java.security.properties` system property) and removing SHA1 usage SignedJAR & denyAfter 2019-01-01 from the `jdk.certpath.disabledAlgorithms` security property and SHA1 denyAfter 2019-01-01 from the `jdk.jar.disabledAlgorithms` security property.



Tenable has extracted the preceding description block directly from the Fedora security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected 1:java-1.8.0-openjdk package.
