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: CVE-2018-19364: 9pfs: use-after-free (bz #1651359) CVE-2018-19489: 9pfs: use-after-free renaming files (bz #1653157) CVE-2018-16867: usb-mtp: path traversal issue (bz #1656746) CVE-2018-16872: usb-mtp: path traversal issue (bz #1659150) CVE-2018-20191: pvrdma: uar_read leads to NULL deref (bz #1660315) CVE-2019-6778: slirp: heap buffer overflow (bz #1669072) CVE-2019-3812: Out-of-bounds read in hw/i2c/i2c-ddc.c allows for memory disclosure (bz#1678081) --------------------------------------------------------------------------------ChangeLog: * Thu Mar 21 2019 Cole Robinson - 2:3.0.0-4 - CVE-2018-19364: 9pfs: use-after-free (bz #1651359) - CVE-2018-19489: 9pfs: use-after-free renaming files (bz #1653157) - CVE-2018-16867: usb-mtp: path traversal issue (bz #1656746) - CVE-2018-16872: usb-mtp: path traversal issue (bz #1659150) - CVE-2018-20191: pvrdma: uar_read leads to NULL deref (bz #1660315) - CVE-2019-6778: slirp: heap buffer overflow (bz #1669072) - CVE-2019-3812: Out-of-bounds read in hw/i2c/i2c-ddc.c allows for memory disclosure (bz #1678081) * Tue Dec 18 2018 Adam Williamson - 2:3.0.0-3 - Restore patch to drop phantom 86 key from en-us keymap (bz #1658676) * Fri Nov 16 2018 Cole Robinson - 2:3.0.0-2 - Fix cpu model crash on AMD hosts (bz #1640140) - CVE-2018-15746: seccomp blacklist is not applied to all threads (bz - Fix assertion in address_space_stw_le_cached (bz #1644728) - CVE-2018-10839: ne2000: fix possible out of bound access (bz #1636429) - CVE-2018-17958: rtl8139: fix possible out of bound access (bz #1636729) - CVE-2018-17962: pcnet: fix possible buffer overflow (bz #1636775) - CVE-2018-17963: net: ignore packet size greater than INT_MAX (bz #1636782) - CVE-2018-18849: lsi53c895a: OOB msg buffer access leads to DoS (bz - CVE-2018-18954: ppc64: Out-of-bounds r/w stack access in pnv_lpc_do_eccb (bz #1645442) --------------------------------------------------------------------------------References: [ 1 ] Bug #1651359 - CVE-2018-19364 qemu: 9pfs: Use-after-free due to race condition while updating fid path [fedora-all] https://bugzilla.redhat.com/show_bug.cgi?id=1651359 [ 2 ] Bug #1653157 - CVE-2018-19489 qemu: 9pfs: use-after-free due to race condition in renaming files [fedora-all] https://bugzilla.redhat.com/show_bug.cgi?id=1653157 [ 3 ] Bug #1656746 - CVE-2018-16867 qemu: path traversal in usb_mtp_write_data in hw/usb/dev-mtp.c of the Media Transfer Protocol (MTP)[fedora-all] https://bugzilla.redhat.com/show_bug.cgi?id=1656746 [ 4 ] Bug #1659150 - CVE-2018-16872 qemu: path traversal by host filesystem manipulation in Media Transfer Protocol (MTP) [fedora-all] https://bugzilla.redhat.com/show_bug.cgi?id=1659150 [ 5 ] Bug #1660315 - CVE-2018-20191 qemu: pvrdma: uar_read leads to NULL dereference [fedora-all] https://bugzilla.redhat.com/show_bug.cgi?id=1660315 [ 6 ] Bug #1669072 - CVE-2019-6778 qemu: slirp: heap buffer overflow in tcp_emu() [fedora-all] https://bugzilla.redhat.com/show_bug.cgi?id=1669072 [ 7 ] Bug #1678081 - CVE-2019-3812 qemu: Out-of-bounds read in hw/i2c/i2c-ddc.c allows for memory disclosure [fedora-all] https://bugzilla.redhat.com/show_bug.cgi?id=1678081 --------------------------------------------------------------------------------This update can be installed with the "dnf" update program.
