SCA: security update for org.jenkins-ci.main:jenkins-core (GHSA-26wc-3wqp-g3rp)

critical Tenable Self-Hosted Container Security Plugin ID 408751

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Jenkins versions 2.56 and earlier as well as 2.46.1 LTS and earlier are vulnerable to an unauthenticated
 remote code execution. An unauthenticated remote code execution vulnerability allowed attackers to
 transfer a serialized Java `SignedObject` object to the Jenkins CLI, that would be deserialized using a
 new `ObjectInputStream`, bypassing the existing blacklist-based protection mechanism. We're fixing this
 issue by adding `SignedObject` to the blacklist. We're also backporting the new HTTP CLI protocol from
 Jenkins 2.54 to LTS 2.46.2, and deprecating the remoting-based (i.e. Java serialization) CLI protocol,
 disabling it by default. (CVE-2017-1000353)
