Scientific Linux Security Update : qemu-kvm on SL7.x x86_64

Medium Nessus Plugin ID 88484


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


An out-of-bounds read/write flaw was discovered in the way QEMU's Firmware Configuration device emulation processed certain firmware configurations. A privileged (CAP_SYS_RAWIO) guest user could use this flaw to crash the QEMU process instance or, potentially, execute arbitrary code on the host with privileges of the QEMU process.

This update also fixes the following bugs :

- Incorrect handling of the last sector of an image file could trigger an assertion failure in qemu-img. This update changes the handling of the last sector, and no assertion failure occurs.

After installing this update, shut down all running virtual machines.
Once all virtual machines have shut down, start them again for this update to take effect.


Update the affected packages.
