Ubuntu Security Notice 6686-4 - It was discovered that the DesignWare USB3 for Qualcomm SoCs driver in the Linux kernel did not properly handle certain error conditions during device registration. A local attacker could possibly use this to cause a denial of service. It was discovered that a race condition existed in the Cypress touchscreen driver in the Linux kernel during device removal, leading to a use-after- free vulnerability. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 6702-1 - It was discovered that the NVIDIA Tegra XUSB pad controller driver in the Linux kernel did not properly handle return values in certain error conditions. A local attacker could use this to cause a denial of service. It was discovered that the ARM Mali Display Processor driver implementation in the Linux kernel did not properly handle certain error conditions. A local attacker could possibly use this to cause a denial of service.

Research conducted by Cisco Talos last year uncovered multiple vulnerabilities rated as low severity despite their ability to allow for full arbitrary code execution.

Ubuntu Security Notice 6701-1 - Ruihan Li discovered that the bluetooth subsystem in the Linux kernel did not properly perform permissions checks when handling HCI sockets. A physically proximate attacker could use this to cause a denial of service. It was discovered that the NVIDIA Tegra XUSB pad controller driver in the Linux kernel did not properly handle return values in certain error conditions. A local attacker could use this to cause a denial of service.

Ubuntu Security Notice 6700-1 - It was discovered that the Layer 2 Tunneling Protocol implementation in the Linux kernel contained a race condition when releasing PPPoL2TP sockets in certain conditions, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the ext4 file system implementation in the Linux kernel did not properly handle block device modification while it is mounted. A privileged attacker could use this to cause a denial of service or possibly expose sensitive information.

Ubuntu Security Notice 6699-1 - Reima Ishii discovered that the nested KVM implementation for Intel x86 processors in the Linux kernel did not properly validate control registers in certain situations. An attacker in a guest VM could use this to cause a denial of service. It was discovered that the Quick Fair Queueing scheduler implementation in the Linux kernel did not properly handle network packets in certain conditions, leading to a use after free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Improper Input Validation vulnerability in Apache Hop Engine. This issue affects Apache Hop Engine: before 2.8.0. Users are recommended to upgrade to version 2.8.0, which fixes the issue. When Hop Server writes links to the PrepareExecutionPipelineServlet page one of the parameters provided to the user was not properly escaped. The variable not properly escaped is the "id", which is not directly accessible by users creating pipelines making the risk of exploiting this low. This issue only affects users using the Hop Server component and does not directly affect the client.

Ubuntu Security Notice 6696-1 - Yi Yang discovered that the Hotspot component of OpenJDK 8 incorrectly handled array accesses in the C1 compiler. An attacker could possibly use this issue to cause a denial of service, execute arbitrary code or bypass Java sandbox restrictions. It was discovered that the Hotspot component of OpenJDK 8 did not properly verify bytecode in certain situations. An attacker could possibly use this issue to bypass Java sandbox restrictions.

### Impact Vela pipelines can use variable substitution combined with insensitive fields like `parameters`, `image` and `entrypoint` to inject secrets into a plugin/image and — by using common substitution string manipulation — can bypass log masking and expose secrets without the use of the commands block. This unexpected behavior primarily impacts secrets restricted by the "no commands" option. This can lead to unintended use of the secret value, and increased risk of exposing the secret during image execution bypassing log masking. Given by the following substitution examples: using `parameters` ```yaml steps: - name: example image: <some plugin> secrets: [ example_secret ] parameters: example: $${EXAMPLE_SECRET} ``` using `image` tag ```yaml steps: - name: example image: <some plugin>:latest${EXAMPLE_SECRET} secrets: [ example_secret ] ``` using `entrypoint` as a shim for `commands` ```yaml steps: - name: example image: <some plugin> secre...
