CVE-2019-1003034 – jenkins-job-dsl-plugin: Script security sandbox bypass in Job DSL Plugin (SECURITY-1342)
https://notcve.org/view.php?id=CVE-2019-1003034
A sandbox bypass vulnerability exists in Jenkins Job DSL Plugin 1.71 and earlier in job-dsl-core/src/main/groovy/javaposse/jobdsl/dsl/AbstractDslScriptLoader.groovy, job-dsl-plugin/build.gradle, job-dsl-plugin/src/main/groovy/javaposse/jobdsl/plugin/JobDslWhitelist.groovy, job-dsl-plugin/src/main/groovy/javaposse/jobdsl/plugin/SandboxDslScriptLoader.groovy that allows attackers with control over Job DSL definitions to execute arbitrary code on the Jenkins master JVM. Existe una vulnerabilidad de omisión de sandbox en el plugin Jenkins Job DSL, en versiones 1.71 y anteriores, en job-dsl-core/src/main/groovy/javaposse/jobdsl/dsl/AbstractDslScriptLoader.groovy, job-dsl-plugin/build.gradle, job-dsl-plugin/src/main/groovy/javaposse/jobdsl/plugin/JobDslWhitelist.groovy y job-dsl-plugin/src/main/groovy/javaposse/jobdsl/plugin/SandboxDslScriptLoader.groovy que permite a los atacantes con control sobre las definiciones DSL "Job" ejecutar código arbitrario en el maestro JVM de Jenkins. A flaw was found in the Jenkins Job DSL plugin. Parsing, compilation, and script instantiations provided by a crafted Groovy script could escape the sandbox allowing users to execute arbitrary code on the Jenkins master. The highest risk from this vulnerability is to data confidentiality and integrity as well as system availability. • http://www.securityfocus.com/bid/107476 https://access.redhat.com/errata/RHSA-2019:0739 https://jenkins.io/security/advisory/2019-03-06/#SECURITY-1342 https://access.redhat.com/security/cve/CVE-2019-1003034 https://bugzilla.redhat.com/show_bug.cgi?id=1690663 • CWE-20: Improper Input Validation •
CVE-2019-1003024 – jenkins-plugin-script-security: Sandbox Bypass in Script Security Plugin (SECURITY-1320)
https://notcve.org/view.php?id=CVE-2019-1003024
A sandbox bypass vulnerability exists in Jenkins Script Security Plugin 1.52 and earlier in RejectASTTransformsCustomizer.java that allows attackers with Overall/Read permission to provide a Groovy script to an HTTP endpoint that can result in arbitrary code execution on the Jenkins master JVM. Existe una vulnerabilidad de omisión de sandbox en Jenkins Script Security Plugin, en versiones 1.52 y anteriores, en RejectASTTransformsCustomizer.java, que permite que los atacantes con permisos Overall/Read proporcionen un script de Groovy a un endpoint HTTP que puede resultar en la ejecución de código arbitrario en el JVM maestro de Jenkins. A flaw was found in the Jenkins script security sandbox. The previously implemented script security sandbox protections prohibiting the use of unsafe AST transforming annotations such as @Grab could be circumvented through use of various Groovy language features including the use of AnnotationCollector, import aliasing, and referencing annotation types using their full class name. This allows users with Overall/Read permission, or the ability to control Jenkinsfile or sandboxed Pipeline shared library contents in SCM, to bypass the sandbox protection and execute arbitrary code on the Jenkins master. • http://www.securityfocus.com/bid/107295 https://access.redhat.com/errata/RHSA-2019:0739 https://jenkins.io/security/advisory/2019-02-19/#SECURITY-1320 https://access.redhat.com/security/cve/CVE-2019-1003024 https://bugzilla.redhat.com/show_bug.cgi?id=1684556 • CWE-96: Improper Neutralization of Directives in Statically Saved Code ('Static Code Injection') •
CVE-2019-7221 – Kernel: KVM: nVMX: use-after-free of the hrtimer for emulation of the preemption timer
https://notcve.org/view.php?id=CVE-2019-7221
The KVM implementation in the Linux kernel through 4.20.5 has a Use-after-Free. La implementación KVM en el kernel de Linux, hasta la versión 4.20.5, tiene un uso de memoria previamente liberada. A use-after-free vulnerability was found in the way the Linux kernel's KVM hypervisor emulates a preemption timer for L2 guests when nested (=1) virtualization is enabled. This high resolution timer(hrtimer) runs when a L2 guest is active. After VM exit, the sync_vmcs12() timer object is stopped. • http://lists.opensuse.org/opensuse-security-announce/2019-02/msg00042.html http://packetstormsecurity.com/files/151713/KVM-VMX-Preemption-Timer-Use-After-Free.html http://www.openwall.com/lists/oss-security/2019/02/18/2 https://access.redhat.com/errata/RHBA-2019:0959 https://access.redhat.com/errata/RHSA-2019:0818 https://access.redhat.com/errata/RHSA-2019:0833 https://access.redhat.com/errata/RHSA-2019:3967 https://access.redhat.com/errata/RHSA-2019:4058 https://bugs.chromiu • CWE-416: Use After Free •
CVE-2019-6974 – Linux - 'kvm_ioctl_create_device()' NULL Pointer Dereference
https://notcve.org/view.php?id=CVE-2019-6974
In the Linux kernel before 4.20.8, kvm_ioctl_create_device in virt/kvm/kvm_main.c mishandles reference counting because of a race condition, leading to a use-after-free. En el kernel de Linux en versiones anteriores a la 4.20.8, kvm_ioctl_create_device en virt/kvm/kvm_main.c gestiona de manera incorrecta el conteo de referencias debido a una condición de carrera, lo que conduce a un uso de memoria previamente liberada. A use-after-free vulnerability was found in the way the Linux kernel's KVM hypervisor implements its device control API. While creating a device via kvm_ioctl_create_device(), the device holds a reference to a VM object, later this reference is transferred to the caller's file descriptor table. If such file descriptor was to be closed, reference count to the VM object could become zero, potentially leading to a use-after-free issue. • https://www.exploit-db.com/exploits/46388 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=cfa39381173d5f969daf43582c95ad679189cbc9 http://www.securityfocus.com/bid/107127 https://access.redhat.com/errata/RHBA-2019:0959 https://access.redhat.com/errata/RHSA-2019:0818 https://access.redhat.com/errata/RHSA-2019:0833 https://access.redhat.com/errata/RHSA-2019:2809 https://access.redhat.com/errata/RHSA-2019:3967 https://access.redhat.com/errata/RHSA-2020:0103 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
