Jan Beulich discovered that the KVM svm hypervisor implementation in the Linux kernel did not properly catch Debug exceptions on AMD processors. An attacker in a guest virtual machine could use this to cause a denial of service (system crash) in the host OS. (CVE-2015-8104)
郭永刚 discovered that the ppp implementation in the Linux kernel did not ensure that certain slot numbers are valid. A local attacker with the privilege to call ioctl() on /dev/ppp could cause a denial of service (system crash). (CVE-2015-7799)
It was discovered that the virtual video osd test driver in the Linux kernel did not properly initialize data structures. A local attacker could use this to obtain sensitive information from the kernel. (CVE-2015-7884)
It was discovered that the driver for Digi Neo and ClassicBoard devices did not properly initialize data structures. A local attacker could use this to obtain sensitive information from the kernel. (CVE-2015-7885)
The Cloud Foundry project released a BOSH stemcell version 3146.1 and 3160 that has the patched version of the Linux kernel.
Affected Products and Versions
Severity is medium unless otherwise noted.
- All versions of Cloud Foundry BOSH stemcells prior to 3160 are vulnerable, besides patched versions of 3146.x.
Users of affected versions should apply the following mitigation:
- The Cloud Foundry project recommends that Cloud Foundry deployments run with BOSH stemcells 3160 or later versions, or patched 3146.x versions.
