SUSE SLED12 / SLES12 Security Update : qemu (SUSE-SU-2016:2879-1)

Critical Nessus Plugin ID 95283

Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for qemu to version 2.6.2 fixes the several issues. These security issues were fixed :

- CVE-2016-7161: Heap-based buffer overflow in the .receive callback of xlnx.xps-ethernetlite in QEMU (aka Quick Emulator) allowed attackers to execute arbitrary code on the QEMU host via a large ethlite packet (bsc#1001151).

- CVE-2016-7170: OOB stack memory access when processing svga command (bsc#998516).

- CVE-2016-7466: xhci memory leakage during device unplug (bsc#1000345).

- CVE-2016-7422: NULL pointer dereference in virtqueu_map_desc (bsc#1000346).

- CVE-2016-7908: The mcf_fec_do_tx function in hw/net/mcf_fec.c did not properly limit the buffer descriptor count when transmitting packets, which allowed local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) via vectors involving a buffer descriptor with a length of 0 and crafted values in bd.flags (bsc#1002550).

- CVE-2016-7995: Memory leak in ehci_process_itd (bsc#1003612).

- CVE-2016-8576: The xhci_ring_fetch function in hw/usb/hcd-xhci.c allowed local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) by leveraging failure to limit the number of link Transfer Request Blocks (TRB) to process (bsc#1003878).

- CVE-2016-8578: The v9fs_iov_vunmarshal function in fsdev/9p-iov-marshal.c allowed local guest OS administrators to cause a denial of service (NULL pointer dereference and QEMU process crash) by sending an empty string parameter to a 9P operation (bsc#1003894).

- CVE-2016-9105: Memory leakage in v9fs_link (bsc#1007494).

- CVE-2016-8577: Memory leak in the v9fs_read function in hw/9pfs/9p.c allowed local guest OS administrators to cause a denial of service (memory consumption) via vectors related to an I/O read operation (bsc#1003893).

- CVE-2016-9106: Memory leakage in v9fs_write (bsc#1007495).

- CVE-2016-8669: The serial_update_parameters function in hw/char/serial.c allowed local guest OS administrators to cause a denial of service (divide-by-zero error and QEMU process crash) via vectors involving a value of divider greater than baud base (bsc#1004707).

- CVE-2016-7909: The pcnet_rdra_addr function in hw/net/pcnet.c allowed local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) by setting the (1) receive or (2) transmit descriptor ring length to 0 (bsc#1002557).

- CVE-2016-9101: eepro100 memory leakage whern unplugging a device (bsc#1007391).

- CVE-2016-8668: The rocker_io_writel function in hw/net/rocker/rocker.c allowed local guest OS administrators to cause a denial of service (out-of-bounds read and QEMU process crash) by leveraging failure to limit DMA buffer size (bsc#1004706).

- CVE-2016-8910: The rtl8139_cplus_transmit function in hw/net/rtl8139.c allowed local guest OS administrators to cause a denial of service (infinite loop and CPU consumption) by leveraging failure to limit the ring descriptor count (bsc#1006538).

- CVE-2016-8909: The intel_hda_xfer function in hw/audio/intel-hda.c allowed local guest OS administrators to cause a denial of service (infinite loop and CPU consumption) via an entry with the same value for buffer length and pointer position (bsc#1006536).

- CVE-2016-7994: Memory leak in virtio_gpu_resource_create_2d (bsc#1003613).

- CVE-2016-9104: Integer overflow leading to OOB access in 9pfs (bsc#1007493).

- CVE-2016-8667: The rc4030_write function in hw/dma/rc4030.c allowed local guest OS administrators to cause a denial of service (divide-by-zero error and QEMU process crash) via a large interval timer reload value (bsc#1004702).

- CVE-2016-7907: The pcnet_rdra_addr function in hw/net/pcnet.c allowed local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) by setting the (1) receive or (2) transmit descriptor ring length to 0 (bsc#1002549).

The update package also includes non-security fixes. See advisory for details.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
