[USN-2773-1] Linux kernel vulnerabilities

Severity Medium

CVEs 2

Several security issues were fixed in the kernel.

It was discovered that virtio networking in the Linux kernel did not handle
fragments correctly, leading to kernel memory corruption. A remote attacker
could use this to cause a denial of service (system crash) or possibly
execute code with administrative privileges. (CVE-2015-5156)

It was discovered that the Reliable Datagram Sockets (RDS) implementation
in the Linux kernel did not verify sockets were properly bound before
attempting to send a message, which could cause a NULL pointer dereference.
An attacker could use this to cause a denial of service (system crash).
(CVE-2015-6937)
