fedora
Calendar Grey August 18, 2015
Dist Fedora Esm H88
Important revision for Fedora 22 tackling various vulnerabilities in qemu to improve overall security and operational efficiency.
* Rebased to version 2.3.1 * Fix crash in qemu_spice_create_display (bz #1163047) * Fix qemu-img map crash for unaligned image (bz #1229394) * CVE-2015-3209: pcnet: multi-tmd buffe...

Summary

QEMU is a generic and open source processor emulator which achieves a good

emulation speed by using dynamic translation. QEMU has two operating modes:

* Full system emulation. In this mode, QEMU emulates a full system (for

example a PC), including a processor and various peripherials. It can be

used to launch different Operating Systems without rebooting the PC or

to debug system code.

* User mode emulation. In this mode, QEMU can launch Linux processes compiled

for one CPU on another CPU.

As QEMU requires no host kernel patches to run, it is safe and easy to use.

Update Information:

* Rebased to version 2.3.1 * Fix crash in qemu_spice_create_display (bz #1163047) * Fix qemu-img map crash for unaligned image (bz #1229394) * CVE-2015-3209: pcnet: multi-tmd buffer overflow in the tx path (bz #1230536) * CVE-2015-3214: i8254: out-of-bounds memory access (bz #1243728) * CVE-2015-5158: scsi stack buffer overflow (bz #1246025) * CVE-2015-5154: ide: atapi: heap overflow during I/O buffer memory access (bz #1247141) * CVE-2015-5166: BlockBackend object use after free issue (bz #1249758) * CVE-2015-5745: buffer overflow in virtio-serial (bz #1251160) * CVE-2015-5165: rtl8139 uninitialized heap memory information leakage to guest (bz #1249755)
