Descripción: | Summary: The remote host is missing an update for the 'qemu' package(s) announced via the referenced advisory.
Vulnerability Insight: This update for qemu fixes several issues.
These security issues were fixed:
- CVE-2017-9330: USB OHCI Emulation in qemu allowed local guest OS users to cause a denial of service (infinite loop) by leveraging an incorrect return value (bsc#1042159).
- CVE-2017-8379: Memory leak in the keyboard input event handlers support allowed local guest OS privileged users to cause a denial of service (host memory consumption) by rapidly generating large keyboard events (bsc#1037334).
- CVE-2017-8309: Memory leak in the audio/audio.c allowed remote attackers to cause a denial of service (memory consumption) by repeatedly starting and stopping audio capture (bsc#1037242).
- CVE-2017-7493: The VirtFS, host directory sharing via Plan 9 File System(9pfs) support, was vulnerable to an improper access control issue. It could occur while accessing virtfs metadata files in mapped-file security mode. A guest user could have used this flaw to escalate their privileges inside guest (bsc#1039495).
- CVE-2017-7377: The v9fs_create and v9fs_lcreate functions in hw/9pfs/9p.c allowed local guest OS privileged users to cause a denial of service (file descriptor or memory consumption) via vectors related to an already in-use fid (bsc#1032075).
- CVE-2017-8086: A memory leak in the v9fs_list_xattr function in hw/9pfs/9p-xattr.c allowed local guest OS privileged users to cause a denial of service (memory consumption) via vectors involving the orig_value variable (bsc#1035950).
- CVE-2017-5973: A infinite loop while doing control transfer in xhci_kick_epctx allowed privileged user inside the guest to crash the host process resulting in DoS (bsc#1025109)
- CVE-2017-5987: The sdhci_sdma_transfer_multi_blocks function in hw/sd/sdhci.c allowed local OS guest privileged users to cause a denial of service (infinite loop and QEMU process crash) via vectors involving the transfer mode register during multi block transfer (bsc#1025311).
- CVE-2017-6505: The ohci_service_ed_list function in hw/usb/hcd-ohci.c allowed local guest OS users to cause a denial of service (infinite loop) via vectors involving the number of link endpoint list descriptors (bsc#1028184)
- CVE-2016-9603: A privileged user within the guest VM could have caused a heap overflow in the device model process, potentially escalating their privileges to that of the device model process (bsc#1028656)
- CVE-2017-7718: hw/display/cirrus_vga_rop.h allowed local guest OS privileged users to cause a denial of service (out-of-bounds read and QEMU process crash) via vectors related to copy ...
