crewjam/saml go library is vulnerable to signature bypass via multiple Assertion elements

The crewjam/saml go library prior to version 0.4.9 is vulnerable to an authentication bypass when processing SAML responses containing multiple Assertion elements. This issue has been corrected in version 0.4.9. There are no workarounds other than upgrading to a fixed version.

Cap'n Proto vulnerable to out-of-bounds read due to logic error handling list-of-list.

Cap'n Proto is a data interchange format and remote procedure call (RPC) system. Cap'n Proro prior to versions 0.7.1, 0.8.1, 0.9.2, and 0.10.3, as well as versions of Cap'n Proto's Rust implementation prior to 0.13.7, 0.14.11, and 0.15.2 are vulnerable to out-of-bounds read due to logic error handling list-of-list. This issue may lead someone to remotely segfault a peer by sending it a malicious message, if the victim performs certain actions on a list-of-pointer type. Exfiltration of memory is possible if the victim performs additional certain actions on a list-of-pointer type. To be vulnerable, an application must perform a specific sequence of actions, described in the GitHub Security Advisory. The bug is present in inlined code, therefore the fix will require rebuilding dependent applications. Cap'n Proto has C++ fixes available in versions 0.7.1, 0.8.1, 0.9.2, and 0.10.3. The `capnp` Rust crate has fixes available in versions 0.13.7, 0.14.11, and 0.15.2.

openshift: insecure default DNSPolicy for pods

A flaw was found in Openshift. A pod with a DNSPolicy of "ClusterFirst" may incorrectly resolve the hostname based on a service provided. This flaw allows an attacker to supply an incorrect name with the DNS search policy, affecting confidentiality and availability.

Openshift: Missing X-Frame-Options Header

The response header has not enabled X-FRAME-OPTIONS, Which helps prevents against Clickjacking attack.. Some browsers would interpret these results incorrectly, allowing clickjacking attacks.

OpenShift: Missing HTTP Strict Transport Security

Openshift 4.9 does not use HTTP Strict Transport Security (HSTS) which may allow man-in-the-middle (MITM) attacks.

Incorrect Authorization in imgcrypt

The imgcrypt library provides API exensions for containerd to support encrypted container images and implements the ctd-decoder command line tool for use by containerd to decrypt encrypted container images. The imgcrypt function `CheckAuthorization` is supposed to check whether the current used is authorized to access an encrypted image and prevent the user from running an image that another user previously decrypted on the same system. In versions prior to 1.1.4, a failure occurs when an image with a ManifestList is used and the architecture of the local host is not the first one in the ManifestList. Only the first architecture in the list was tested, which may not have its layers available locally since it could not be run on the host architecture. Therefore, the verdict on unavailable layers was that the image could be run anticipating that image run failure would occur later due to the layers not being available. However, this verdict to allow the image to run enabled other architectures in the ManifestList to run an image without providing keys if that image had previously been decrypted. A patch has been applied to imgcrypt 1.1.4. Workarounds may include usage of different namespaces for each remote user.

Denial of Service of protobuf-java parsing procedure

An issue in protobuf-java allowed the interleaving of com.google.protobuf.UnknownFieldSet fields in such a way that would be processed out of order. A small malicious payload can occupy the parser for several minutes by creating large numbers of short-lived objects that cause frequent, repeated pauses. We recommend upgrading libraries beyond the vulnerable versions.

DoS in SnakeYAML

Using snakeYAML to parse untrusted YAML files may be vulnerable to Denial of Service attacks (DOS). If the parser is running on user supplied input, an attacker may supply content that causes the parser to crash by stackoverflow.

OpenShift: selinux-policy privilege escalation to reveal process listing

selinux-policy as packaged in Red Hat OpenShift 2 allows attackers to obtain process listing information via a privilege escalation attack.

cxf: CXF's STSClient uses a flawed way of caching tokens that are associated with delegation tokens

Apache CXF's STSClient before 3.1.11 and 3.0.13 uses a flawed way of caching tokens that are associated with delegation tokens, which means that an attacker could craft a token which would return an identifer corresponding to a cached token for another user.

libffi requests an executable stack allowing attackers to more easily trigger arbitrary code execution by overwriting the stack. Please note that libffi is used by a number of other libraries. It was previously stated that this affects libffi version 3.2.1 but this appears to be incorrect. libffi prior to version 3.1 on 32 bit x86 systems was vulnerable, and upstream is believed to have fixed this issue in version 3.1.

jenkins-plugin-workflow-cps: Arbitrary code execution due to incomplete sandbox protection (SECURITY-551)

Arbitrary code execution due to incomplete sandbox protection: Constructors, instance variable initializers, and instance initializers in Pipeline scripts were not subject to sandbox protection, and could therefore execute arbitrary code. This could be exploited e.g. by regular Jenkins users with the permission to configure Pipelines in Jenkins, or by trusted committers to repositories containing Jenkinsfiles.

jenkins-plugin-script-security: Unsafe methods in the default whitelist (SECURITY-538)

The default whitelist included the following unsafe entries: DefaultGroovyMethods.putAt(Object, String, Object); DefaultGroovyMethods.getAt(Object, String). These allowed circumventing many of the access restrictions implemented in the script sandbox by using e.g. currentBuild['rawBuild'] rather than currentBuild.rawBuild. Additionally, the following entries allowed accessing private data that would not be accessible otherwise due to script security: groovy.json.JsonOutput.toJson(Closure); groovy.json.JsonOutput.toJson(Object).

jenkins-plugin-git: CSRF vulnerability allows capturing credentials (SECURITY-528)

Git Plugin connects to a user-specified Git repository as part of form validation. An attacker with no direct access to Jenkins but able to guess at a username/password credentials ID could trick a developer with job configuration permissions into following a link with a maliciously crafted Jenkins URL which would result in the Jenkins Git client sending the username and password to an attacker-controlled server.

jenkins-plugin-pipeline-build-step: Missing check of Item/Build permission (SECURITY-433)

Builds in Jenkins are associated with an authentication that controls the permissions that the build has to interact with other elements in Jenkins. The Pipeline: Build Step Plugin did not check the build authentication it was running as and allowed triggering any other project in Jenkins.

jenkins-plugin-subversion: CSRF vulnerability and insufficient permission checks allow capturing credentials (SECURITY-303)

Subversion Plugin connects to a user-specified Subversion repository as part of form validation (e.g. to retrieve a list of tags). This functionality improperly checked permissions, allowing any user with Item/Build permission (but not Item/Configure) to connect to any web server or Subversion server and send credentials with a known ID, thereby possibly capturing them. Additionally, this functionality did not require POST requests be used, thereby allowing the above to be performed without direct access to Jenkins via Cross-Site Request Forgery attacks.

OSE 2 cookie does not set httponly

Red Hat OpenShift Enterprise 2 does not include the HTTPOnly flag in a Set-Cookie header for the GEARID cookie, which makes it easier for remote attackers to obtain potentially sensitive information via script access to the cookies.

kibana: XSS vulnerability ESA-2016-03

Kibana before 4.5.4 and 4.1.11 are vulnerable to an XSS attack that would allow an attacker to execute arbitrary JavaScript in users' browsers.

kibana: Session hijack via stealing cookies and auth headers from log ESA-2016-04

Kibana before 4.5.4 and 4.1.11 when a custom output is configured for logging in, cookies and authorization headers could be written to the log files. This information could be used to hijack sessions of other users when using Kibana behind some form of authentication such as Shield.

OpenShift3: Private Docker images can be used by any user, once they are pulled to a node

Kubernetes in OpenShift3 allows remote authenticated users to use the private images of other users should they know the name of said image.
