Scientific Linux Security Update : spice-server on SL6.x x86_64

Critical Nessus Plugin ID 91647


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


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.

The CVE-2016-0749 issue was discovered by Jing Zhao (Red Hat) and the CVE-2016-2150 issue was discovered by Frediano Ziglio (Red Hat).


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