CVE-2020-10721

A flaw was found in the fabric8-maven-plugin 4.0.0 and later. When using a wildfly-swarm or thorntail custom configuration, a malicious YAML configuration file on the local machine executing the maven plug-in could allow for deserialization of untrusted data resulting in arbitrary code execution...

jenkins-2-plugins/matrix-project: Stored XSS vulnerability in multiple axis builds tooltips

A flaw was found in the Matrix Project Plugin version 1.16 and prior. Node names shown in tooltips are not escaped on the overview page of builds with multiple axes which could lead to a stored cross-site scripting XSS vulnerability. The user must have the Agent/Configure permission for this...

kernel: metadata validator in XFS may cause an inode with a valid, user-creatable extended attribute to be flagged as corrupt

A flaw was found in the Linux kernel. A failure of the file system metadata validator in XFS can cause an inode with a valid, user-creatable extended attribute to be flagged as corrupt. This can lead to the filesystem being shutdown, or otherwise rendered inaccessible until it is remounted, leadi...

kernel: memory corruption in net/packet/af_packet.c leads to elevation of privilege

A flaw was found in the Linux kernel. Memory corruption can be exploited to gain root privileges from unprivileged processes. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability...
