Incorrect signature verification of the firmware during the Device Firmware Update process of Belkin Wemo Smart Plug WSP080 v1.2 allows attackers to cause a Denial of Service (DoS) via a crafted firmware file.

Uncovered issues fall into use-after-free, buffer-overflow, information leak and denial of service vulnerability classes. Some of these could be combined to achieve remote code execution or privilege escalation.

Ubuntu Security Notice 6228-1 - It was discovered that the XFS file system implementation in the Linux kernel did not properly perform metadata validation when mounting certain images. An attacker could use this to specially craft a file system image that, when mounted, could cause a denial of service. Wei Chen discovered that the InfiniBand RDMA communication manager implementation in the Linux kernel contained an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of service.

Ubuntu Security Notice 6227-1 - Several security issues were discovered in the SpiderMonkey JavaScript library. If a user were tricked into opening malicious JavaScript applications or processing malformed data, a remote attacker could exploit a variety of issues related to JavaScript security, including denial of service attacks, and arbitrary code execution.

Ubuntu Security Notice 6226-1 - It was discovered that SciPy did not properly manage memory operations during reference counting. An attacker could possibly use this issue to cause a denial of service. A use-after-free was discovered in SciPy when handling reference counts. An attacker could possibly use this to cause a denial of service. This issue only affected Ubuntu 20.04 LTS.

Ubuntu Security Notice 6225-1 - It was discovered that Knot Resolver did not correctly handle certain client options. A remote attacker could send requests to malicious domains and cause a denial of service.

Ubuntu Security Notice 6224-1 - It was discovered that the XFS file system implementation in the Linux kernel did not properly perform metadata validation when mounting certain images. An attacker could use this to specially craft a file system image that, when mounted, could cause a denial of service. Wei Chen discovered that the InfiniBand RDMA communication manager implementation in the Linux kernel contained an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of service.

Ubuntu Security Notice 6223-1 - It was discovered that the TUN/TAP driver in the Linux kernel did not properly initialize socket data. A local attacker could use this to cause a denial of service. It was discovered that the Real-Time Scheduling Class implementation in the Linux kernel contained a type confusion vulnerability in some situations. A local attacker could use this to cause a denial of service.

Ubuntu Security Notice 6222-1 - Jiasheng Jiang discovered that the HSA Linux kernel driver for AMD Radeon GPU devices did not properly validate memory allocation in certain situations, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service. Zheng Wang discovered that the Intel i915 graphics driver in the Linux kernel did not properly handle certain error conditions, leading to a double-free. A local attacker could possibly use this to cause a denial of service.

Ubuntu Security Notice 6221-1 - It was discovered that a race condition existed in the overlay file system implementation in the Linux kernel. A local attacker could use this to cause a denial of service. It was discovered that the virtual terminal device implementation in the Linux kernel contained a race condition in its ioctl handling that led to an out-of-bounds read vulnerability. A local attacker could possibly use this to expose sensitive information.
