Summary
Red Hat Security Advisory: OpenShift Container Platform 4.5.13 jenkins security update

Notes

Topic
An update for jenkins is now available for Red Hat OpenShift Container Platform 4.5. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Jenkins is a continuous integration server that monitors executions of repeated jobs, such as building a software project or jobs run by cron. Security Fix(es): * jetty: double release of resource can lead to information disclosure (CVE-2019-17638) * jenkins: user-specified tooltip values leads to stored cross-site scripting (CVE-2020-2229) * jenkins: stored XSS vulnerability in project naming strategy (CVE-2020-2230) * jenkins: stored XSS vulnerability in 'trigger builds remotely' (CVE-2020-2231) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

When this happens, the ByteBuffer containing the HTTP response headers is released back to the ByteBufferPool twice. Because of this double release, two threads can acquire the same ByteBuffer from the pool and while thread1 is about to use the ByteBuffer to write response1 data, thread2 fills the ByteBuffer with other data. Thread1 then proceeds to write the buffer that now contains different data. This results in client1, which issued request1 seeing data from another request or response which could contain sensitive data belonging to client2 (HTTP session ids, authentication credentials, etc.). If the Jetty version cannot be upgraded, the vulnerability can be significantly reduced by configuring a responseHeaderSize significantly larger than the requestHeaderSize (12KB responseHeaderSize and 8KB requestHeaderSize).",
