critical Nessus Plugin ID 91514

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

Security Fix(es) :

 - A memory allocation flaw, leading to a heap-based buffer overflow, was found in spice's smartcard interaction, which runs under the QEMU-KVM context on the host. A user connecting to a guest VM using spice could potentially use this flaw to crash the QEMU-KVM process or execute arbitrary code with the privileges of the host's QEMU-KVM process. (CVE-2016-0749)

 - A memory access flaw was found in the way spice handled certain guests using crafted primary surface parameters.
 A user in a guest could use this flaw to read from and write to arbitrary memory locations on the host.
 (CVE-2016-2150)

Solution

Update the affected spice-debuginfo, spice-server and / or spice-server-devel packages.
