A flaw was found in the Linux kernel's udmabuf device driver. The specific flaw exists within a fault handler. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an array. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the kernel.

Google has opened up its software-dependency database, adding to the security data available to developers and toolmakers. Now developers need to use it.

Ubuntu Security Notice 6020-1 - It was discovered that the System V IPC implementation in the Linux kernel did not properly handle large shared memory counts. A local attacker could use this to cause a denial of service. It was discovered that the KVM VMX implementation in the Linux kernel did not properly handle indirect branch prediction isolation between L1 and L2 VMs. An attacker in a guest VM could use this to expose sensitive information from the host OS or other guest VMs.

Debian Linux Security Advisory 5388-1 - It was reported that HAProxy, a fast and reliable load balancing reverse proxy, does not properly initialize connection buffers when encoding the FCGI_BEGIN_REQUEST record. A remote attacker can take advantage of this flaw to cause an information leak.
