Fedora 21: qemu Security Update 2015-13404
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:
* Fix crash in qemu_spice_create_display (bz #1163047) * 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-2015-5154: ide: atapi: heap overflow during I/O buffer memory access (bz #1247141) * CVE-2015-5745: buffer overflow in virtio-serial (bz #1251160) * CVE-2015-5165: rtl8139 uninitialized heap memory information leakage to guest (bz #1249755)
