response headers, Jetty throws an exception to produce an HTTP 431 error. 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).", "title": "Vulnerability description" }, { "category": "summary", "text": "jetty: double release of resource can lead to information disclosure", "title": "Vulnerability summary" }, { "category": "general", "text": "The CVSS score(s) listed for this vulnerability do not reflect the associated product\u0027s status, and are included for informational purposes to better understand the severity of this vulnerability.", "title": "CVSS score applicability" } ], "product_status": { "fixed": [ "7Server-RH7-RHOSE-4.3:jenkins-0:2.235.5.1600415514-1.el7.noarch", "7Server-RH7-RHOSE-4.3:jenkins-0:2.235.5.1600415514-1.el7.src" ], "known_not_affected": [ "8Base-RHOSE-4.3:openshift-0:4.3.37-202009120213.p0.git.0.dffefe4.el8.src", "8Base-RHOSE-4.3:openshift-hyperkube-0:4.3.37-202009120213.p0.git.0.dffefe4.el8.ppc64le", "8Base-RHOSE-4.3:openshift-hyperkube-0:4.3.37-202009120213.p0.git.0.dffefe4.el8.s390x", "8Base-RHOSE-4.3:openshift-hyperkube-0:4.3.37-202009120213.p0.git.0.dffefe4.el8.x86_64" ] }, "references": [ { "category": "self", "summary": "Canonical URL", "url": "https://access.redhat.com/security/cve/CVE-2019-17638" }, { "category": "external", "summary": "RHBZ#1864680", "url": "https://bugzilla.redhat.com/show_bug.cgi?id=1864680" }, { "category": "external", "summary": "https://www.cve.org/CVERecord?id=CVE-2019-17638", "url": "https://www.cve.org/CVERecord?id=CVE-2019-17638" }, { "category": "external", "summary": "https://nvd.nist.gov/vuln/detail/CVE-2019-17638", "url": "https://nvd.nist.gov/vuln/detail/CVE-2019-17638" }, { "category": "external", "summary": "https://bugs.eclipse.org/bugs/show_bug.cgi?id=564984", "url": "https://bugs.eclipse.org/bugs/show_bug.cgi?id=564984" }, { "category": "external", "summary": "https://www.jenkins.io/security/advisory/2020-08-17/", "url": "https://www.jenkins.io/security/advisory/2020-08-17/" } ], "release_date": "2020-06-03T00:00:00+00:00", "remediations": [ { "category": "vendor_fix", "date": "2020-09-23T12:46:15+00:00", "details": "For OpenShift Container Platform 4.3 see the following documentation, which\nwill be updated shortly for this release, for important instructions on how\nto upgrade your cluster and fully apply this asynchronous errata update:\n\nhttps://docs.openshift.com/container-platform/4.3/release_notes/ocp-4-3-release-notes.html\n\nDetails on how to access this content are available at\nhttps://docs.openshift.com/container-platform/4.3/updating/updating-cluster-cli.html.", "product_ids": [ "7Server-RH7-RHOSE-4.3:jenkins-0:2.235.5.1600415514-1.el7.noarch", "7Server-RH7-RHOSE-4.3:jenkins-0:2.235.5.1600415514-1.el7.src" ], "restart_required": { "category": "none" }, "url": "https://access.redhat.com/errata/RHSA-2020:3808" } ], "scores": [ { "cvss_v3": { "attackComplexity": "HIGH", "attackVector": "NETWORK", "availabilityImpact": "LOW", "baseScore": 7.7, "baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:L", "version": "3.1" }, "products": [ "7Server-RH7-RHOSE-4.3:jenkins-0:2.235.5.1600415514-1.el7.noarch", "7Server-RH7-RHOSE-4.3:jenkins-0:2.235.5.1600415514-1.el7.src" ] } ], "threats": [ { "category": "impact", "details": "Important" } ], "title": "jetty: double release of resource can lead to information disclosure" }, { "cve": "CVE-2020-2220", "cwe": { "id": "CWE-79", "name": "Improper Neutralization of Input During Web Page Generation (\u0027Cross-site Scripting\u0027)" }, "discovery_date": "2020-07-15T00:00:00+00:00", "flags": [ { "label": "vulnerable_code_not_present", "product_ids": [ "8Base-RHOSE-4.3:openshift-0:4.3.37-202009120213.p0.git.0.dffefe4.el8.src", "8Base-RHOSE-4.3:openshift-hyperkube-0:4.3.37-202009120213.p0.git.0.dffefe4.el8.ppc64le", "8Base-RHOSE-4.3:openshift-hyperkube-0:4.3.37-202009120213.p0.git.0.dffefe4.el8.s390x", "8Base-RHOSE-4.3:openshift-hyperkube-0:4.3.37-202009120213.p0.git.0.dffefe4.el8.x86_64" ] } ], "ids": [ { "system_name": "Red Hat Bugzilla ID", "text": "1857425" } ], "notes": [ { "category": "description", "text": "A flaw was found in Jenkins versions 2.244 and prior and in LTS 2.235.1 and prior.
