RHSA-2022:1021

A flaw was found in the way HAProxy processed HTTP responses containing the "Set-Cookie2" header. This flaw could allow an attacker to send crafted HTTP response packets which lead to an infinite loop, eventually resulting in a denial of service condition. The highest threat from this vulnerability is availability.

Jenkins Pipeline: Groovy Plugin 2648.va9433432b33c and earlier uses the same checkout directories for distinct SCMs when reading the script file (typically Jenkinsfile) for Pipelines, allowing attackers with Item/Configure permission to invoke arbitrary OS commands on the controller through crafted SCM contents.

Jenkins Pipeline: Shared Groovy Libraries Plugin 552.vd9cc05b8a2e1 and earlier uses the same checkout directories for distinct SCMs for Pipeline libraries, allowing attackers with Item/Configure permission to invoke arbitrary OS commands on the controller through crafted SCM contents.

Jenkins Pipeline: Groovy Plugin 2648.va9433432b33c and earlier follows symbolic links to locations outside of the checkout directory for the configured SCM when reading the script file (typically Jenkinsfile) for Pipelines, allowing attackers able to configure Pipelines to read arbitrary files on the Jenkins controller file system.

Jenkins Pipeline: Shared Groovy Libraries Plugin 552.vd9cc05b8a2e1 and earlier follows symbolic links to locations outside of the expected Pipeline library when reading files using the libraryResource step, allowing attackers able to configure Pipelines to read arbitrary files on the Jenkins controller file system.

Jenkins Pipeline: Shared Groovy Libraries Plugin 552.vd9cc05b8a2e1 and earlier does not restrict the names of resources passed to the libraryResource step, allowing attackers able to configure Pipelines permission to read arbitrary files on the Jenkins controller file system.

Jenkins Pipeline: Groovy Plugin 2648.va9433432b33c and earlier includes password parameters from the original build in replayed builds, allowing attackers with Run/Replay permission to obtain the values of password parameters passed to previous builds of a Pipeline.

A sandbox bypass vulnerability in Jenkins Pipeline: Shared Groovy Libraries Plugin 552.vd9cc05b8a2e1 and earlier allows attackers with Item/Configure permission to execute arbitrary code in the context of the Jenkins controller JVM through crafted SCM contents, if a global Pipeline library already exists.

A sandbox bypass vulnerability in Jenkins Pipeline: Shared Groovy Libraries Plugin 552.vd9cc05b8a2e1 and earlier allows attackers with Item/Configure permission to execute arbitrary code on the Jenkins controller JVM using specially crafted library names if a global Pipeline library is already configured.

Jenkins Pipeline: Shared Groovy Libraries Plugin 552.vd9cc05b8a2e1 and earlier uses the names of Pipeline libraries to create cache directories without any sanitization, allowing attackers with Item/Configure permission to execute arbitrary code in the context of the Jenkins controller JVM using specially crafted library names if a global Pipeline library configured to use caching already exists.

Jenkins Pipeline: Build Step Plugin 2.15 and earlier reveals password parameter default values when generating a pipeline script using the Pipeline Snippet Generator, allowing attackers with Item/Read permission to retrieve the default password parameter value from jobs.
